    If you check out the review posted in the sedan topic it even mentions the weak A/C. Even in big bold letters it states "WEAK AIR CONDITIONING CAPACITY."

    http://www.autosite.com/Reviews/2004-mazda-3.asp

    "However, the air conditioner’s ability to cool the cabin was deemed questionable during a springtime heat wave that sent temperatures soaring above 100 degrees in downtown Los Angeles. High temperatures, a black interior, and leather seats require deep-freeze A/C capability, and the Mazda 3 did not deliver – Phoenix residents considering the 2004 Mazda 3, be warned."

    Here lies the problem though. It doesn't sound like it's not working at all, just that it's weak. And since the writer probably drives numerous cars all the time there's definetly something wrong. So since it may be "weak" in most cars and not outright not working (although some may not have any cool air coming out at all) then it may explain why some people don't complain. Depending on climate and how much they use the A/C some people will find it acceptable.

    I know you're impatient but using the G35 example again it took a solid 6 months to get it fixed. On top of that the G35/Skyline was out several months beforehand in Japan. They may have already found the cause and are now working on getting the parts ordered and together. THEN they have to be able to send a sufficient amount to each dealer. They probably also want to make sure the fix they may have found will work on a long-term basis before wasting the time and effort and money on getting a fix to dealers that may fail. There could be any number of things going on we don't know about.

    Bottomline is they acknowledged the problem and also reviews are starting to pick up on it so you better believe they aren't going to sit on their hands. Not sure if you can lemon law a car on the A/C not being fixed. I think you need documentation that they tried a certain number of times to fix it. Of course if they're saying everything is normal you won't get very far.

    So what do you do? You're doing the first thing. Spread the word and cost them some sales. I don't know if that'll "speed up" the process of a fix any but if I bought a brand new car with a non-working A/C I'd be mad too. And if it becomes too little too late boycott the brand. That's exactly what I plan to do when I buy my next car based on past experiences. I know every company has lemons but cars are expensive and I at least expect the company and dealership to work with me to fix it and stand behind the product.

    I have read the review you posted. Problem is I bought my Mazda3 on January 21, 2004. This article was written May 31, 2004. I had already found out that the Mazda3 has a defective AC system - the hard way!

    modock
    I don't understand your post - you say " If you wanted a car that would immediately have cool air then you will have to pay more than the $16K we both paid for our cars"

    But you also post "I had a 92 Nissan 240SX which I consider to have had a great AC system"

    Did you pay more that $16K for the 92 Nissan?

    I think if you flip the two statements around you'll understand what modock was trying to say. Makes a little more sense like this:

    "I had a 92 Nissan 240SX which I consider to have had a great AC system [but] If you wanted a car that would immediately have cool air then you will have to pay more than the $16K we both paid for our cars."

    "Such evaluation can sometimes even include countermeasures to be developed in the future, as is possible with the A/C cycling for the MAZDA3 (i.e., yes, our technical services and research have been contacted about the opinions that customers have shared with us about the cycling of the MAZDA3, as it was designed). Any developments would go directly through your dealership and their regionally-placed Mazda
    Quality Assurance technical resources, however, and not any corporate offices."

    We need to keep up the pressure by publicizing this issue.

    On the other hand, I just refilled the gas tank on my 3S today: 11.7 gallons and 430 miles; that's 36.6mpg. I am sure that the undersized a/c unit helps allow better mileage. But, since it's cooling is so minimal, I wonder how much better the mileage might be with no a/c unit?

    rs4184: From my experience, your fuel gauge is way off. I usually have 120-130 miles before the gauge shows the first 1/4 tank gone. The low fuel light had not come on yet when I refueled today. It usually comes on when I have less than two gallons left.
  • oldmonkoldmonk Member Posts: 38
    A part of the reply that I received on the AC problem - sounds exactly the same.

    "We do take customer feedback quite seriously. If this IS related to the
    normal operation of the system and you are not satisfied with the
    performance, be assured, I have already documented your comments
    regarding it. These records are constantly reviewed by both our product
    planning department and our technical service department to evaluate.
    Such evaluation can sometimes even include countermeasures to be
    developed in the future, as is possible with the A/C cycling for the
    MAZDA3. Any developments would go directly through your dealership and
    their regionally-placed Mazda Quality Assurance technical resources,
    however, and not any corporate offices."

    36 mpg??? I cant even dream of such a number with my mazda3 hatch. I dont get above 25 mpg, even with the AC not being cool or even turned on...
  • aric214aric214 Member Posts: 20
    My A/C has been having problems as well. It's very sporadic; sometimes its ice cold and other times it's just cool air. But either way, the passengers in the back are never really 100% comfortable on a hot sunny day. I agree with Pzev: I think the best thing to do is to be patient and publicize the issue. There isn't really much we can do right now...

    Waygrabow - In regards to fuel efficiency, do you do mostly highway driving? My 3i (purchased in Jan. 2004) gets about 27-29 city and 33-35 highway.

    Oldmonk - I had the same problem when I first got the car (averaging 23-25 mpg). I called the service dept at my Mazda dealership and they told me it needs to "break-in." According to them, after the 3rd oil change (~10k miles), things should be up to par. Pretty long warm up period, I think...
  • z71billz71bill Member Posts: 1,986
    I called the Mazda 800 number yesterday to ask about the AC issue. At first they claimed that this was the first that they have heard about any AC problems in the Mazda3. After I told them Mazda had already sent me an E-mail that indicated Mazda was aware of the problem and it was being worked on - the tune changed - we do not have a TSB for this problem and no repairs can be made.

    I ask - What should I do to get my problem resolved?

    Mazda answer - I can give you a web site that you can go to every few weeks and it will list all of the TSB that are issued. If/when Mazda issues a TSB on the AC of the Mazda3 it will be posted on this site.

    Turns out the site is the National Highway safety / transportation web site -

    I ask - So Mazda's idea of customer service is to send me to a government web site?

    Yes - at this time that is all Mazda can do - until a TSB is issue no repairs can be authorized.

    Mazda customer service is a JOKE.
  • oldmonkoldmonk Member Posts: 38
    I am surprised to hear "sometimes its ice cold", is that when the outside weather itself is cold?

    >> "According to them, after the 3rd oil change (~10k miles), things should be up to par"

    I have 16K miles already!
  • aric214aric214 Member Posts: 20
    Suprisingly, no. Although, it happens once in a blue moon. But damn, those blue moons don't come around often anymore :P
  • jsnschmasnjsnschmasn Member Posts: 10
    Thank you for contacting Mazda North American Operations. I appreciate
    the opportunity to respond to you.

    In regard to your inquiry, Mazda is aware of the A/C concerns you're
    experiencing with your MAZDA3. Our Product Engineering Department is
    currently investigating this concern with the Engineers in Japan. We
    hope to have a resolution very soon. I certainly apologize for any
    inconvenience this has caused you.
  • oldmonkoldmonk Member Posts: 38
    That reply from Mazda sounds much better. Is this a very recent response?
  • backybacky Member Posts: 18,949
    I saw the other day that the weather has been very hot in Tokyo recently, humid with temperatures around 95. Perhaps this will help Mazda in their problem determination.
  • z71billz71bill Member Posts: 1,986
    I got the same reply from Mazda on May 12.

    I sent a reply E-mail to Mazda around June 15th to ask them if any progress had been made finding a solution to the problem - They did not even bother to respond, I sent a second reply - Maybe the first one was lost - still no reply.

    I think Mazda is using the "we know about the concern - engineers are investigating" as a stall. What they say may be true - they know about it and are investigating - but that does not mean they are going to do anything about it.

    When I called Mazda 800 number Tuesday they acted like they had never had anyone even complain about the AC before.

    In response to z71bill -- Well, I picked up my brand spanking new Mazda3S yesterday afternoon.

    As you suggested, I point blank asked the customer rep. how they would respond if the A/C did not perform to my expectations. At first he didn't give a direct response, but eventually said "we will do whatever it takes to correct the problem". He had no idea how they would determine whether or not the A/C is working to spec -- he kept telling me that out of the several dozen M3's they've sold, no complaints about A/C yet. Of course in the Boston area the temperature has barely gone over 80 degrees this summer (so far).

    It'll be interesting to see what happens when the first REAL heat wave comes!

    Regardless, the experience of driving the M3 home yesterday was absolutely exhilarating -- Mazda has really come up with an excellent car design. By far the best I've ever owned.
  • perritoperrito Member Posts: 66
    So, I guess most people are concerned with the weak A/C system, and no one else has a starting problem? When the car has been resting overnight, or in the sun, the car shakes when trying to start it; it does, but only after about 5-6 seconds of rattle and roll. Anybody else have this? Did Mazda have a fix, or at least, a diagnosis? Anyone? perrito
  • z71billz71bill Member Posts: 1,986
    I sincerely hope you have a car that does not have the AC or any other defect. I agree the Mazda3 is a great little car - IMO it has the right balance between ride- handling - power - economy (cost to buy and cost to drive)- sporty looks - interior room & safety -

    Since you live in a much cooler climate you may never experience the AC issue -

    If you are unlucky enough to experience problems I wonder what your dealer will do - I can only guess that they would fall back on the old - Mazda won't authorize any repairs -our hands are tied - the system is working as designed -BS that they are giving me.
  • bluedolphinbluedolphin Member Posts: 4
    Thanks for your supportive comments. Sorry your experience has been less than satisfying. This is my fourth Mazda vehicle since buying a GLC Sport hatchback in 1982 -- and my experience has been trouble-free.

    As a matter of fact, as I look at the recent post about cold-starting problems (perrito), it occurs to me that the only vehicle of mine to have a serious design flaw was the 1998 Corolla that I just traded in for the M3. It seems so ironic that the one vehicle (out of five I've owned over a 20-year period) with a major annoyance was a Toyota. So much for build quality reputation.

    Perrito's problem sounds just like what happened to my brand new Corolla in 1998 -- after several trips to the dealer it turns out the fuel pump was defective. Once they replaced the pump the problem never came back in my six-plus years of ownership. Just a thought.
  • gandrigogandrigo Member Posts: 87
    You are not alone in the hard start category, though mine does not have problems idling once it does catch. I am currently waiting on a new fuel pump that is back ordered. I think there is a TSB out for that problem, and the fuel pump replacement addresses it. i am also waiting on the modified mounting bracket for the front brakes to silence the screech. I am also amongst the complainants with regards to the Air conditioning, and about as annoyed with Mazda's response as others. as a final note, mine has an intermittent hesitation problem under acceleration that is driving me insane, and that the dealership can't reproduce or feel when i demonstrate it to them. Great little car when working correctly, but mine definitely has issues. this is my fourth Mazda, and though I don't buy into the arguement that Honda or Toyota have the edge in reliability or quality, Mazda's customer service leaves alot to be desired.

    Just curious to see if anyone has had any problems with the A/C with tinted windows or tan interior w/o tinting. For most people the interior of these cars are black. Black absorbs heat. Lots of it. In a hatchback, like I have, there is a lot of glass and lots of black interior to absorb it. I say this because I have another car that is black on black with dark tint without much cooling problems. As for hot sunny days in South Florida, i too think the A/C in the Mazda is weak. I would suggest tinting for one. Cools the car, saves the interior and it looks good.

    Here is a link for a list of TSBs on the Mz3.

  • waygrabowwaygrabow Member Posts: 214
    When I got 36.6mpg on my most recent fill-up I think that is about as good as I can expect (although Consumers Reports got 42 mpg highway on a 3i). For this tankful, I used my 3S MT mainly as a commuter on a 22 mile route over county roads with about six stop signs/lights and speed limits of 45-55 mph. I have about 8800 miles on the car; so it is fairly well broken in. I never get less than 33 mpg per tank full. I am fairly careful about not tailgating, and watching the color of the next traffic light so that I don't keep switching between the brake and gas pedals. Generally I do "push" the speed limits though. Interstate speeds do cost gas mileage; a steady 55-60 mph is probably best. The Mazda3 doesn't have the guts to be a stoplight racer, so I don't even try that game.
  • jsnschmasnjsnschmasn Member Posts: 10
    I posted a short while ago regarding a clicking noise coming from the left lower dash of my 3i m/t when travelling over anything but smooth pavement. I had the dealer check it out and had to drive with the tech for him to hear it. It's been in the shop for a few days and while the dealership is very nice they said they drove 4 different 3i sedans and all of them had the slight clicking. They said one had it on the opposite side of the dash. They said they called the Mazda rep and explained the issue and that his reply was that this was just a "characteristic" of the car. The dealership said they would try to dampen the noise as best they could but basically if that doesn't work then I'm SOL. I find this hard to stomach.
  • yleeylee Member Posts: 4
    I bought a Mazda 3s 5-door last week. It has about 500 miles so far and I could go 300 miles with almost empty tank before fill-up (like 13g). Driving ratio between highway and city is 40/60 around urban area(washington D.C, not with much heavy traffic when I drive). I don't even drive so fast. I think it should be getting about more than 27 miles per gallon with manual transmission in highway and city mixing. I don't know why I feel that I get lower mileage. Is it because something with fuel pump that had to be changed when I bought it before even leaving dealership or it is because it is a new car? I would like to hear other opinions.
  • z71billz71bill Member Posts: 1,986
    The Mazda3 is rated 24 city 29 highway - so 27 MPG with 40% highway and 60% city your MPG sounds about right - I don't understand how you could expect much better.

    I was getting 22 MPG - but then my CEL came on - after three trips to the dealer the CEL light is off - but now I am getting around 19 MPG - lowest tank was 17 - I have not been over 20 since my CEL "repair". I would take 27 MPG any day.

    Well, yesterday was all I could take. I took some co-workers out for lunch and it was so hot in the car, the guy in the back was dying, and after the 10 min commute to the place we were eating, the car was still horrible! We got out, and the air hit the sweat in our shirts and it felt NICE! Cooler outside than in the car? Crazy! You feel the air coming out of the vent and it seems cool. When the temps were 80 degrees, the A/C seemed fine, and when reading this forum the last few months I was hoping I had a good A/C. Now thats the temps are mid to high 90's...I'm cooking!I had to fly to Oklahoma Monday and Tuesday of this week, and rented a Chevy Cavalier. Oklahoma was HOT, and that Cav cooled things down REAL nice! it was a 4 door like my 3, so it wasnt that the cabin was smaller, and the temp was in the 90's. My 2003 Suburban will freeze you out after 5-10 min in the car...but 10 min in the 3 you are still sweating! I see what y'all are talking about now that the temp is in the high 90's here in Texas. I have a black car too, but they should have taken a black car, no tint, in 100 degree weather and spec'd the A/c to cool the extremes. I am going to start with the dealer, bring it in, and see what they say, then email Mazda, and document everything. The two guys who rode with me wanted a 3 like mine. After yesterday, they arent saying how nice it is, they are talking about OTHER cars that they like, and one guy is going to buy an Element instead now. It is sad when you cant take your car for lunch without stressing over your passengers being uncomfortable. Guess I will be keeping a very watchful eye on this forum, and if I get any revelations, I will pass it on as well. I just might be trading this thing in, getting killed on the upsidedown-ness, but I cant deal with a weak A/C here in Texas! We will see.
  • z71billz71bill Member Posts: 1,986
    When I first started reading your post I thought it was one I had posted about 2 months ago.

    I also took some friends to lunch in my car - when we got out of the car one guy said - next time we go to lunch lets take my car it has an AC that works. A little embarrassing - yes - more so when you know his car is a 1990 something Honda Civic with over 200K.

    I hate to give you the bad news but chances are if you have cool air coming out of your vents your dealer will tell you that the AC is up to Mazda's (low) standards. When the dealer told me this I ask what the standard for cooling is - seemed like a fair question - if a car is "up to standard" - turns out that means cool air is coming out of the vent and the system has a certain PSI reading. It has nothing about actually cooling the car.

    Mazda customer service department is a complete JOKE - they do not have a clue what customer service even means - the 800 number and Mazda E-mail service do nothing.

    One of the bigger kicks in the groin is when you call Mazda at 800 222 5500 you get to hear a recorded message - "Have you seen the great new Mazda3 - best small car in the world - bla bla bla" - Kind of adds insult to injury
  • yleeylee Member Posts: 4
    I forgot to mention what I got from 300 miles. It was about 23 MPG (300miles/13g). What I meant by 27 MPG was that this is the mileage I should be getting. And I am amazed by the fact that you are getting 19-23 MPG. Is anyone else getting lower mileage? Can it be fixed?
  • oldmonkoldmonk Member Posts: 38
    Welcome to the A/C issue club klrss! I hope the size of this A/C issue community grows rapidly and the word gets spread fast so Mazda does something to avoid potential customers turn to other brands...
  • harddrivetharddrivet Member Posts: 90
    Does the 6 or RX have these same AC issues?
  • lmp180psulmp180psu Member Posts: 399
    I know the RX-8 has a TSB out concerning insufficient & inconsistent cooling - something to do with an "A/C Amplifier" problem ( I posted a link to it a few weeks ago in this forum). Not sure about the Mazda6.

    I am also in the "club" and have taken it to the dealer to check it out, and have been given the "temperature and pressure is within manufacturer specs" response. I hate having to clean my door panels from dog drool/saliva, since it takes forever for any cool air to get to the back of my sedan :( I still love the car otherwise (aside from annoying rear brake dust).
  • oldmonkoldmonk Member Posts: 38
    exactly lmp180psu, AC and the rear brake dust are the annoying ones. And the wind noise (when traveling with window(s) open) is generally higher and irksome than any other that I have been in, other than that it is a nice car. And the mileage could be better too..., oh yes paint chips is one more on the downside...
  • klrssklrss Member Posts: 28
    Thanks for the Welcome guys! I wish I wasnt part of the group, but hey...Mazda Suckered me in with a fun car, great looks and nice options! ha! One thing I would comment on as well is the Stereo, It it not that good as far as I am concerned. When you crank the bass up, it gets real muddy. I will take my 3 in next week sometime for the A/C. Hate to do it, because I know what I am in for, and the response I will get, but atleast I will have a paper trail. I am the kind though that will see if they will fix it, call Mazda, do a dance for a while then just trade it in and get something else. Now is the time to test drive cars too...it's HOT!!! Hey, and I noticed the cycling too yesterday. When I get into it, it seems that when the throttle gets to a certain point it kicks the A/C out to save power..ok, fine...but i was on the freeway just cruising and the air just gets warm all of a sudden. I felt it immediately since the air is blowing right on my face. And thats another thing...you have to put all vents on your face to make you feel like things are working, which in turn dries your eyes out! ok...nuff A/C bashing, I am sure y'all dont need details, I am preaching to the chior. :)
  • z71billz71bill Member Posts: 1,986
    My theory is the amount of freon in the system - even when it is filled to Mazda specs - is not sufficient to allow the compressor to keep running.

    Compare the amount of R134A that is considered a full charge:

    Mazda3 17.55 ounces
    Nissan PU 22.5 ounces (28% more)
    Chevy Silverado (reg & X-cab) 28.8 ounces (64% more)
    Chevy Tahoe 48 ounces (173% more)

    Maybe someone can post the amount of R134A that some other vehicles require - so we can see if Mazda3 is really on the low end as far as quantity of freon the system holds.

    There is a label under the hood that will indicate how much R134A the system requires.

    I would be interested to know how much freon a Mazda6 holds - or a Honda Civic - Toyota Corolla.
  • audia8qaudia8q Member Posts: 3,138
    the label on the MZ6 says 1.1 lb of HFC-134a
  • mazda6smazda6s Member Posts: 1,901
    Hmmm, the MZ6 has 1.1lbs which is 17.6oz and is the same (within a decimal digit) of the 17.55oz in the MZ3. So, my theory is that it's the programming in the AC controller that's messed up. Of course, as I software guy I should always blame the hardware, but in this case I suspect it's not. ;)
  • npaladin2000npaladin2000 Member Posts: 593
    Probably running Windows...have to wait for His Royal Gates-ness to issue a patch. ;)
  • z71billz71bill Member Posts: 1,986
    If the Mazda6 uses 1.1 pounds - then that is the exact same as the Mazda3. The under hood label of the 3 says 1.1 pounds, 17.6 ounces. The owners manual of the 3 says 17.55 ounces. Must be rounding.

    That theory is shot down - I have not read of anyone having problems with the 6.

    I have thought that the software could be the problem - but it seems like if that was all that was wrong it would not take Mazda so long to fix it - and a program update would only take a few minutes and be a small cost - compared to replacing parts anyway.

    With the temperature in Houston hitting 95 degrees it sure would be nice to have a killer AC instead of a weak piece of crap.

    I am looking at buying a 3 at some point and was on the Mazda3 Axela forum, so I apologize (since I am new to this forum) if this has been repeated:

    Apparently, there is no insulation around some of the A/C hoses that come into the 3 from under the hood. These hoses happen to be near "hotter" parts of the components under the hood. I should know more, but at the moment, I can't find that part of the thread.

    From those posts, it is not uncommon for other cars to have insulation around those hoses to keep the processed cool air in a cool state.

    Does anyone know anything about this?
  • lmp180psulmp180psu Member Posts: 399
    I think you are violating an Edmunds rule about posting links to "competing forums".

    I belong/participate to/in the forum you refer to, and no one has come up with a definitive cause to the subpar AC performance. It could be lack of insulation, but I don't think the member you refer to ever gave an update on the "fix" or not.

    Hopefully that will be the solution :)
  • npaladin2000npaladin2000 Member Posts: 593
    I'm a member of that forum too. I've got the link bookmarked should Edmunds delete the link to it, so if anyone needs it, send an e-mail asking.
  • dewrightdewright Member Posts: 5
    I read the "rules of the road" and deleted the post about there being no insulation on the hoses under the Mazda3 hood that run A/C into the car. Don't know how valid of a diagnosis this is.

    Sorry for breaking "forum decorum".

    I am terribly disappointed in my gas mileage so far. I live in Georgia, United States. It's warm and beautiful here. Of course, this means I drive with the air conditioner on almost all the time. I have a 2.3L five speed Mazda3 wagon. There are about 2000 miles on the car. I haven't done a first oil change yet. Still, the absolute highest gas mileage I have gotten was 24 miles per gallon, and that was 100% highway on a road trip! Around town I've gotten 19 or 20 miles per gallon consistently on every fill-up. My driving style is moderate. I usually shift just a tad higher than the owner's manual mentions. I shift into neutral anytime I'm coming to a stop. I do open the engine up to nearly red-line about once on every tank of gas. (Gotta' have some fun, right? ;-) With my driving style, my location, and the fact that the magazines I've read say they're getting HIGHER than advertised gas mileage on their long-term test vehicles, I'm having trouble believing there's not more going on here than just a break-in period. What do you guys think?
  • imontoyaimontoya Member Posts: 29
    I am getting about 25 MPG combined driving in my automatic Mazda3 hatchback. The A/C is kind of weak but where I live I only need it about 2 weeks out of the year. I love owning a car where the only complaints are really superficial (brake dust, A/C) or subjective (stereo system). This car has great for and to me! I can't believe someone is complaining about open window wind noise - that is too funny!
  • harddrivetharddrivet Member Posts: 90
    I have a 3i MT.
    We noticed this weekend with heavy Boston area humidity the AC was not as effective at full blast to cool the car as my Pontiac or Nissan do. Perhaps you folks have a valid case. You would think with such a small sized car the Max setting would cause you in the least to get the chills. I hope Mazda can be convinced to make it better.
  • z71billz71bill Member Posts: 1,986
    imontoya - I do not understand how anyone could consider a major defect in the AC system to be superficial. Next time the temp gets up over 80 degrees - roll your windows UP - turn your HEATER to max - when your shirt is soaked with sweat then maybe you will begin to understand what I am talking about. Superficial my butt.

    harddrivet - The thing I notice when driving my other vehicles - I point the vents so they are NOT blowing air right at me - it gets too cold even when the fan speed is turned down on low.

    I like this car too. But that does not mean that you need to be happy with everything, the wind noise may be of least concern to you since you may be driving with everything shut all the time, I like to enjoy the nice air outside and on the highways if I keep the windows open I end up closing it soon since it is noisy...I am comparing it to my 92 eclipse.

    Nevertheless it is best to complain here so other people can know what to expect if they buy this car. A bad A/C may be a superficial issue for you since you need it only for 2 weeks in a year, but not so for many other people...

    What is funny is: you dont want to hear negative things about this car since you paid so much money and you like it a lot! You should probably not be looking at the "mazda3 problems" discussions since you are perfectly happy anyways.

    To all posters on these topics--

    As an owner of an '03.5 Mazda ES and an '03.5 P5 Protege, I have read all your posts with interest.

    1) Re: AC. What are the specs of the Mazda 3 system compared to the Protege? The AC in both of our vehicles is excellent, regardless of driving environment. In the hottest climates--Tucson, Albuquerque, Las Vegas, etc., we can use "2" on the blower, with temp at coldest and it's more than adequate. This, in 100+ degree temps. In fact, we've owned a number of Mazdas and never had a complaint about the heating/cooling systems.

    Looking at the laundry list of Mazda TSBs, I don't see one for a "weak" Protege AC system, regardless of year. Why now?

    2) Re: Mileage. The Protege 2.0L engine isn't considered to be a top-mileage engine, and an automatic will be worse than a stick, although driving habits can alter that. Both our cars have cold air intakes, aftermarket cat-back exhaust systems, iridium plugs and, on the P5, an overbored throttle body. Both cars are quicker than stock, thus tend to be driven "spiritedly."

    That said, I pass the following #s along for comparos: both cars average 27-33 mpg depending on city/hiway use; a working figure over a period of time would settle in around 29-30. Frankly. I expected less based on our driving habits.

    Example: this past week, we drove the ES 1500 miles from Denver to Las Vegas and back. We averaged 27+, at an average speed of over 75 with AC running most of the time.

    Maybe we're lucky?

    I picked up my new Mazda3 GT last week. So far, I love the car, but am quite concerned about the ventilation system. I live in a part of Canada where we seldom need air conditioning, but I often want fresh air at the outside temperature blowing into the car. A few nights ago, I was sitting in my driveway idling for a short while, trying to figure out the sound system. It was getting warm in the car so I turned on the fan with the temperature set at the coldest and the air directed to the dashboard vents. I received a prolonged blast of very warm air. It was a cool night and air conditioning should not have been required. I have done some further testing and found that the cool air drawn into the hvac system is being noticeably warmed by the engine prior to getting into the system, especially in the case of idling, stop and go driving, and slow city driving. This morning at 6:30 a.m. it was 15 degrees Celsius (59F) and the car was just comfortable with the ventilation fan on 2 and the temperature set to its coldest. There was no sun to speak of at the time, so the car wasn't being heated by the sun. Most of my driving was around 70 kph (around 45 mph), with a few stop lights. In any car, the hvac system will be drawing in air from immediately above the car and there may be a small amount of heating of the air, but this is excessive. My two previous cars were a 92 323 and a 99 Protege. I didn't have this problem with them. If it isn't rectified I will have to use air conditioning on fairly cool days, when I shouldn't have to, if I want air moving through the car. This pre-heating of outside air will be contributing to the air conditioning efficiency problem, especially on the fresh air setting. The air conditioning will have to cool air which has been significantly heated by the engine first. I have reported the problem to Mazda Canada and was advised that they were aware of air conditioning complaints, but not the issue of undue warming of outside air when the air conditioning is off. I would assume if they are looking into a fix for the air conditioning, they will discover this is a contributing factor and fix it at the same time. Just in case, if others are having this problem, it would be best to report it to Mazda. I spoke with a co-worker who picked up a Mazda3 the day before me. He said he had been running the air conditioning a lot, but assumed that it was just hot outside. He is now going to check whether the incoming fresh air appears hotter than the outside air. Others may want to do the same.

    Hmm...so you're saing the A/C "problem" might not be a problem with the A/C system at all, but a seperate component of the car?

    Why does that seem SO familiar for some reason? ;) THIS is why it takes so long to do testing and issue fixes on something "simple" like A/C not cooling enough...

    Well I didn't pay "so much money" for this car. But I also realize that this car is a first year run as well. The dearth of problems is encouraging. I have had an Acura CL-S and a BMW 328is with similar wind noise and more rattles inside than the Mazda3. I do agree the brake dust and weak A/C is annoying and I can't wait to hear Mazda do something about it.
