Mitsubishi Endeavor Maintenance and Repair

SiMrEman07

I was trying to change the dome light bulb in the trunk in my '04 Endeavor XLS, and I think I shorted something out out, My interior lights won't go on, the radio won't go on and my remote won't work either. The LCD display says "Communication Error". I checked all the fuses and they're all good, don't know if its a relay or solonoid or something else. Anyone familiar with this problem before I take it to the dealer? Please help!!!! :confuse: :confuse:

BTW I only have 37,000 miles on the car and I purchased it new, if this makes a difference.

I had the same problem and found out the drain is incorporated in the body so I drilled my own drain hole and put my own drain tube in. I also found out that on the intake to the ac inlet had no screening so it was allowing crap to get in to clog the drain in the fist place so I put a screen in myself and never had a problem since. All you have to do is pop the plastic grill under the passenger windshield wiper off to get access and then just duct tape some aluminum window screening in place.

I have a 2004 Endeavor, we recently had a mass air sensor replaced, now I noticed that the floorboards and carpet on the driver side is soaking wet, what could be causing this? the car is not running hot, the radiator is far away from the control panel on the drivers side, plus it is not leaking.

I have had my 2007 Endeavor for a few months. Now that we have very cold weather in New England I use my heating system every day. It works OK but not as well as I expected. I also have a Dodge Grand Caravan and the heating system is so much stronger there - it can warm up the car in half the time the Endeavor's does. I took my Endeavor to a mechanic and he said that it is normal for Mitsubishi cars to have weaker heating systems and Dodge cars are known for having stronger heating systems overall. How would you rate your Endeavor's heating system compared to other cars you have or had before.

We have a 2004 Endeavor and a 2007 Galant and these guys heat up quicker than anything else we've ever had over the last 40 years. And that's real important in upstate New York!

Why was your mass air sensor replaced? What symptoms were you experiencing?

hellcat51

Why does your mass air sensor need to be replaced? What symptoms were you experiencing?

dthomas4

I have a 2004 Endeavor and had to replace the mass air sensor or something close to that name, I thought it was bad fuel, but after it was replaced the car runs fine.but before that it would turn over and never start and emit black smoke.

gerbytop

I have the same two cars and your right the Dodge will run you out. This is my first winter with the endeavor. It heats up twice as fast but does not get the cabin temperature up too fast. I switch it to the floor setting and you get it blowing in the back seat it does help. Is your car/engine seem loud. I am trying to get over it but it gets on my nerves.

dthomas4

The endeavor acted as though it was bad gas, and emitted black smoke when we tried to start the car. But when we tried to start the car, it either wouldn't start or start and it idled very badly and then go dead, we had to have it towed to have it repaired.

bstensgard

I have had my '04 for 2.5 years now and it seems to run quiet when you are idling or cruising. However, when accelerating it seems to get louder. Its always been that way and we haven't had to bring it in yet. Knock on wood.

This is the first Minnesota winter it has really seen (Texas car) and the engine is much louder in the bitter cold.

The heating system usually works fine, but in this -50F weather it does have trouble warming up the cab.

gerbytop

it was only 24f this morning. I hit the button to recirc the air and it got pretty hot. I will try again tomorrow it will be 2 degrees. good luck!

chrisbond09

Yes, I think the engine is quite loud. It also makes all kinds of different noises when you switch into a gear, especially with reverse gear. As far as the heat goes it takes so much longer to defrost the windows in Endeavor as opposed to Dodge Grand Caravan. I also think I have a problem with floor heat setting. I don't think there is any air coming out. How much heated air do you have coming out at the floor on the driver's side?

barbourman

My car is having the same problem this morning. I had to rent a car. Do you know the exact part that fixed the problem? Your help would be very appreciated.

Thanks

gerbytop

I had alot of air blowing out when on the floor setting. It makes more noise when it is on this setting.

:confuse: Please let me know if you've found a solution. This just started on my 2004 XLS AWD (104,000 miles). I can only open it from the inside release lever. I stop by a mechanic (not the dealer) who looked at fuses, etc. but nothing.

homburgpokes

Thanks for your response. Thought I'd follow up nearly 3 years on.

You're right, and my ignorance of cars shows. The car does turn over, but it never starts. Now three years later the problem continues. Every 5 months or so the car won't start. If you have ever lost the programming in a key, the same type of thing happens, except the immobilizer 'key' light on the dashboard will flash. In our case, the light never flashes. The dealership has reprogrammed the keys several times. The remotes have been in and out of operation, including the new one we purchased. 3 years on, and we have not found a resolution. When the problem happens, we merely hold the key over until the car starts...often a minute or more.

I'm still in favor of replacing the ECU, but I'd like to have some proof before we do that.

No black smoke emits or any such thing.

homburgpokes

The problem continues three years on. I just posted a lengthy reply to one of the original responses. If I hold the key to start it for over a minute, maybe pump the gas, it will start....eventually. Let me know if you fixed the problem as well.

josh99216

I too have an 04 endeavor and it is unbelievably fast at heating up and blows strong hot air. I've owned many vehicles (trucks cars 1 minivan and several SUV's) mostly Daimler Chrysler products and none of them even came close to heating the way my endeavor does. I love it!!

snglmommyinoc

YES! I am the original owner of my Black 2004 Mitsubishi Endeavor and it is about 40-50% oxidized. The roof of the car is 100% white. I read that this was caused by Mitsubishi skimping on the factory clear coat on only their black vehicles from 2003-2005. I called Mitsubishi and apparantely they were willing to re-paint JUST THE OXIDIZED PARTS! I was so upset. They would paint only the hood, one door panel and the roof of my car and leave the rest so it would be a beautiful uneven mess, and the parts they don't paint will most likely begin to oxidize in the near future and they will paint it piece by piece. :mad: Makes a lot of sense right?? Not
They have in a round about way admitted fault for this but, don't want to take care of it. My car has 96,993 miles on it and the tranny is starting to fail :sick: . I really hope it goes in the next thousand miles or so because I have the 100,000 mile power train warranty and they won't repair it until the transmission is completely shot. I will never buy a Mitsubishi again. :lemon: I have had to replace the catalytic converter 4 times, had water leak onto my floor board, had a really bad exhaust leak and when I took it to Mitsubishi to repair, I got it back with none of the power outlets working and my power seat not working when those were just fine when I brought it in! lol

04 Endeavor with water leak on driver's side. Tires Plus said R/R evaporator and replace seal $773. Dealer service mgr said $2 part and $900 job. Good private mechanic said water is leaking from somewhere around the evaporator, but didn't want to undertake taking out dash. Any better ideas?

hellcat51

Any specifics on the transmission failing? Symptoms, etc.? I have a 2004 AWD and it does not shift smoothly. Jerks a lot and clunks.

vedermania

I have a 2007 endeavor with the following problem:

The blower on the heater works for all locations except when the front windshield defogger. The air is blowing, but it is not coming out at all by the windshield. I do not know where to look or what to look for to try and fix this.

Any suggestions? It clearly is something mechanical, but what?

crasyendevor

please cant you help me with that problem the last week spend $145 and the same leak came again thanks

mitsubishi endevor 04 leaks when it rains and was told it will cost $93 per hour to find the problem. The problem is a manufacturer defect in design.My front passenger side is soaked when it rains and since it doesnt dry properly mold is growing in my car because I can see it. It doesn't take long to grow. my eyes burn when I get in to drive and I live in Florida so it rains a lot. I've had to stop wearing contacts and went to a eye specialist for a year until I realized it's the mold in the car. I can't avoid the rain in Florida so now my eyes are going to be the problem because of a manufacturer defect that is not being fixed. I smell a lawsuit because I can't afford $93 per hour to find a leak. I've already paid too much to repaint the peeling paint job because of sloppy and cheap manufacturer cost saving strategy that obviously didn't think of the consumer coming back to gripe.

concreteboy

i believe your leak is in the evaporator . this is common due to the fact that the endeavor's drain is poorly designed. what happens is that the drain hole underneath the car is plugged. it doesn't take much to plug it either. the water backs up to the evap and leaks on to the passsenger side of the floor. i took mine to the dealer and he wanted 500.00 to see if he could fix it. i took it home and did it myself for nothing.
jack up your car. be sure to put jack stands underneath. on the driver side, at the bottom of the firewall, there are 2 brake lines that run along there. behind the brake lines there is a hole about the size of your little finger. it will take you a little while to locate it because you can't really see it unless you have a mirror. it is directly behind the lines and almost impossible to find. once you locate it you will have to take some wire to stick up in there and wiggle it around as much as you can untill you get through the dirt in the hole. once you do that, be prepared to get soaked because the water will be coming. i also cleaned it out with my air compressor. no more leak, no more mold since. it was a hassle but at least the dealer didn't get my money.

ackeegrl

thanks for that info. I will buy a six pack and see if that will get someone more knowledgeable than me to go for this challenge without taking out my brake line. Excuse my ignorance but since it only leaks when it rains what role does the evaporator play in draining rain water which should have never entered the car in the first place?

concreteboy

good idea for the 6 pack, but you don't have to take off the brake lines at all. allthough the hole is right behind the lines, you can still get a piece of wire up in there. if you are absolutely sure that yours leaks only when it rains, then check firewall and floor area on the passenger side for a missing or craked floor pan grommet. another way of telling if you are leaking from the evap tray, is to put some dry paper towel on the floor and drive your car around. if your tray is full of water, it will leak more when you make right and left turns. if you get water, that means your tray is full and you need to free the drain line like i said. either way, try it out before you take it to the dealer unless you got the money.

majvic

my leak is only on the driver's side. I'm holding off until I find out more or have time to get under there myself.
majvic

ackeegrl

U R Gr8! I appreciate your info. I printed your instructions and sent my 18 yr old son under the suv to check it out. It took him a while to find the hole and yes he did need that mirror. He found the hole and said the wire went in left and also to the right but he couldnt get it to go in far either way.....so I didn't get to see him get soaked with water.did you have to go straight up with that wire or did you see 2 areas to go left or right? it's an 04 endeavor. we didnt have to put it on a jack since the SUV sits high off the ground. is it possible that hole is not clogged so I might have another problem? or do I need to drill a hole in the bottom of my truck? I'm desperate at this point.....

bfavors

My girlfriend has a 2004 Endeavor and the headlights are aimed way too low......is there an adjustment ...so far I haven't seen one

ff976

I had the same problem last year with the ac not working. The problem is ignition switch that stick when hot.

angelasig

We have the same problem it is not the light ours had a short in the wireing as a matter of fact we just had it taken care of today,

Now my husband brings it home and I go out to check it and NOW the other rear light is doing the same thing, the brake light works but the rear light while driving is not working at all, we tried new lights it now must be the same wiring problem,

we live far from the dealer so we have to wait until monday to go back, due to work schedules. This is not fair they need to get it right the first time. We have other important things to do.

kaba0528

Did you ever find out what the problem was with the communication error. Same thing just happen to me this weekend>>>>>>Help.

jvuong

So I just picked up my car from a diagnostic of the Check Engine Lights and its bad news. I had codes P0421 and P0431, so when I described to the service analyst the symptoms:
- Lost of Power while Driving, like I'm not stepping on the gas (engine never dies however) :sick:
- When Hard Accelerating, I feel the car stutter a bit

It was confirmed that I have a bad catalytic converter. And its going to cost $2800 to have it repaired!?!? :mad: I've been searching all over the web for a diagram, part, etc (with no luck), and will continue to call a few of the local muffler shops to see if they'll be able to do it, but has anyone had to replace this? My vehicle is an 04 XLS AWD, and unfortunately has 93K miles on it so its outside that federal replacement window.

Does anyone have a diagram of the cat flow, and why it costs so much to replace? Is there a way to buy the part from elsewhere and have it done? Can't seem to find it online anywhere so any guidance/links/support on the matter would be greatly appreciated.

Thanks in advance!

majvic

Estimate from the best AC people to fix is $953. He says bad Mitsubishi design. They used a foam material in the evaporator and it deteriorates in 3 to 5 years. Only fix is pull the dash and replace. GM uses a rubber sponge which never has a problem. This really sucks.

josh99216

WOW! I would definately check around. $2800 to repair a catalytic converter seems outrageous. Where did you take it to get the estimate; The Dealership? I also have an 04 XLS AWD with 56,000 miles and have only had it for about 3 months. I bought the car because all the reviews on it seemed good. Every website I went to had it rated about 4.5 out of 5 stars, but after coming to this site, I am a little concerned.

Definately keep us posted. I am very curious as to the cost to repair that.

ralka

sounds like you have a leak from the body area not the a/c, whole different animal.
could be a body seam could be a w/shield leak , sunroof ?
the a/c will leak if there is a lot of moisture in the air and you use either the a/c of the defrosters ( both activate the compressor) if it is only in the rain than i would look in a different direction

josh99216

I bought my used 04 Mitsubishi Endeavor XLS about 5 months ago with 54K miles on it. It now has 57K miles on it and though I know its a bit early to worry about but I was wondering if someone could tell me when the timing belt should be replaced. I am also curious as to if the timing belt were to break while driving, does this blow the engine? I know some cars timing belts break and it doesnt hurt the engine, how about the 04 Endeavor? Also any other maintenance advice would be greatly appreciated.

ackeegrl

I agree. I use my AC all the time since it's really hot here in florida and I get no leaks. I even pulled up the carpeting and the foam under it to see if it leaks when the AC is on and it doesnt. Only when it rains then the water gathers in the front passenger side where there is a dip for water settling......I'm not sure what it's for but the space under there is large enough to hold a gallon of water and I heard it slushing around so I got fed up and pulled it up and it was full of water. I believe there is mold in my truck from this water staying in the car and I had to go to the eye specialist for a year and they had no idea why my eyes were hurting and now I know. The mold in my car because of the water. That design flaw in the truck is what caused the problem and I shouldnt have to pay $90 per hour to get it fixed. That's the quote I got from the dealer to find the problem. I smell a class action suit. Anyone else has a design flaw like this? I think the manufacturers should do a recall and fix this. I already paid to repaint because they used very little clear coat on the truck and it started peeling after 4 years which should not happen. Poor workmanship based on saving money.

brenda18

I was told this morning by a service writer that replacing the timing belt on my 2005 Mitsubishi Endeavor was very important as it would cause engine failure.

Also, the engine needs to be taken apart to replace the platinum-tipped spark plugs!

Anyone have any idea how carbon gets into solenoid vents in the ignition system?

brenda18

Josh,
Please see my message #385.
Thanks,
Brenda18

brenda18

Be careful when you this serviced, as it takes special oil which only the dealers have. If an outside mechanic buys it, they have to buy the whole container and only use about 1/4 of the container.

ddpr88

Hey guys,

I have a 2005 Endeavor and when i turn it on lately i experience a loss of power while getting out of the parking and when i have to stop at stop signs when the car has just been turned on. Once i rev the engine and drive it for sometime its fine. But the other day i was leaving a park and had to stop at a stop sign before leaving and the car started losing power and eventually turned off. It would not start for like an hour!!! I took it to PepBoys and they said the battery and alternator were working fine...! Help!! Thanks!

amyc62401

HELP! Please tell me you were able to find a solution. This just happened to my car today. I started it and Communication Error showed up on my screen. My automatic key won't work, nor will the radio/cd player. I'm dreading the answer I might get from the dealer

jvuong

Have you checked your Mass Air Flow (MAF) sensor? I had a problem similar to this on my old Nissan Pathfinder and that was what was causing my car to lose power, and in some cases, shut down entirely.

dthomas4

Hello has anyone figured out why and where the air conditioner is draining in the front driver side floorboards? where is the drain located, it is supposed to drain outside and under the car right?

I have a 04 Endevor with 203,000 miles on it. It has been a great car. I did not replace the original timing belt until 175,000 miles. I only did it then because I thought I was pushing my luck by having that many miles on the original. It was a mistake in my case. That belt lasted about 1,000 miles, had to have the engine rebuilt. The next one lasted less than 30,000, got lucky was stopped when it broke and did not have to do anything to the engine. I got less than 1,000 miles on it and am going to have to have the engine rebuilt again. Not sure what the problem is with replacing the belt but there must be a problem of some kind. So be careful. I had it done the first time at a local repair shop and this time had it done at dealer. Didn't seem to make a difference

I have a light silver 2004 Mits Endeavor that looks much older because the paint on the hood and the roof has faded and oxidized so badly. Crown Mits in St. Petersburg, FL said it would cost $4,000-$5,000 to repaint the entire vehicle. I think that's ridiculously high. I might as well "upgrade" to a newer vehicle for that kind of money.
