    Sounds like you solved that problem. This may not apply, but if an owner hasn't changed the in cabin air filter in a looooong time it can affect the performance of ac/heating, as I know it did on mine.

    As I took the vehicle in to get transmission replaced the AC went out. The front and back fans were blowing, but it was warm/hot. After paying $$$$ for transmission, went to my regular mechanic about the AC. He tested it and found it was an "electrical" issue and must see a specialist. Then the specialist took more than a week to determine the computer was going bad and must be replaced. Feeling my pain and understanding I was out $$$$ for the transmission he proposed a Plan B, which was to replace the evaporator temp sensor and rewiring AC to engage when ignition was on and bypassing the faulty circuit. After $$$ paid the AC now starts about two seconds after I turn it on, but the front fan works only at full blast and will not automatically adjust to cabin temperature....

    Now two weeks later the front blow fan does not work at all, but cold air "seeps" slowly from the front vents. The back fan is fine. Specialist took a look and figured the fan motor was deteriorating. Tapping and wiggling it hard caused it to blow harder, but now it won't even respond to that. Specialist recommended replacing the unit, which I have done (thanx AutoZone)...but the new unit still will not engage. Suggestions?
  • I am having the same issues with my wifes 2008 Odyssey. AC randomly stops. Sometimes if we open all the windows and doors - it will again blow cold. Sometimes it will blow cold by starting and stopping; other times it works after turning the heat on for 1-2 minutes.

    Also, the defroster will not clear the windows. this is becoming a safety issue. :mad: :lemon:

    What ended up fixing the blowing hot problem? I've replaced my transistor assembly 2 times without fixing the problem. I need to turn mt temperature control down to 64 before I get cold air. If turn it up past that, it immediately blows hot air.
  • Update: I have not solved the problem. I just adjust the temp to get either hot or cold out of the front as needed. Usually in hot weather, I sent it at 68 or below to get cold. One like suggested it might be either:
    Part # 39794-S0K-A01 RELAY ASSY., POWER (4P) (MICRO ISO) (OMRON), or
    Part # 80560-S0X-A01 THERMISTOR, AIR CONDITIONER.
    A diagram and pictures can be found at (If you put in your Honda Information):

    The relay appears to control the fan, and not be this problem. So it may be the Thermistor? :confuse:

    Thanks for responding. The problem I was having was warm air would blow out of the dash, even with the temperature control off unless I lowered the temperature to 60 degrees. The recirculation light would then come on and finally blow cold. Unfortunately, it was either too hot or too cold. I did resolve the problem. It ended up being a disconnected diverter lever that connects to the air mix motor. The air mix motor is under the dash on the passenger side and to the left. Almost behind the center of the dash. It has a green wire connector attached to it. With the ignition key turned to the on position, I verfied the air mix motor was functioning while turning the temperature knob on the dash back and forth. I noticed a white plastic lever with a long slot in it behind the motor moving, but not moving much. I could manually move it much farther by hand. When I did this I could hear a door opening and closing. I moved the plastic lever all the way the other direction and managed to get it slid over a guide pin attached to the air mix motor. I see the guide pin is suppose to fit in the slot in the lever. After re-attaching, the air works as it should. Not too hot or too cold. I hope this helps anyone else experiencing the same symptoms.
  • Hi folks,
    My front heater and AC are not working. Don't want to spend an arm and a leg if there is something I can do on my own. I see many had this issue on different models. It's cold in winter and would be nice to have the front heater. I am overworking my rear heater (as it works) to heat the car before stepping into the car :-( Please help! Thanks much in advace and a Happy New Year!

    If your fan is not blowing, you will not feel any A.C. Or little heat. If your fan motor will not work on AUTO, but will turn on when maxing out the fan knob, it is most likely the transistor assembly. The part number is listed in these forums. If that is not the case, there are some fuses and relays located in the engine compartment...good luck!
  • Thanks Phx70 - the fan works fine and it blows pretty much outside air at that temperature. When I crank up the temperature, it does not heat up, when I lower it all the way to 60 (in auto mode) it does not kick in the AC. Would appreciate a link to any info.

  • update here - I took the plunge to change the transistor/resistor - cost was $70 and change. Unfortunately it did not appear to fix the issue. I checked out the resistor and transistor on the old one - they seem fine. The cap seems OK as well. So, I am stuck again without heater. Could someone help. BTW, the video in this discussion was extremely helpful to change the transistor/resistor. Trick I used, instead of the screw driver, you can also use a 9/16 hex nut which is much easier than the screwdriver. Anyway, look forward to hearing to some advise. Again, the fan blows fine, but both AC and heater is gone - could it be the thermostat? (also, dealer quote to change the resistor - $149 and he would not budge; I did it in under 35 minutes).

  • About a month ago my 2007 Odyssey suddenly release large amount of freeon while I was driving. The whole fogged up and I first thought it was smoke due to overheat. After pulling off the road and let down the window and shut off the engine. When I started the car again, it didn't happen again. I called Honda Corporate to report the problem and they told me to take it to the dealer which I did. Sadly, they dealer told me that they couldn't duplicate the problem and sent me home, but the service adviser did say that she has seen it happened to another car before. When I searched this problem online, I found out many odysseys have the same problem and mine is not the only one. Just two days ago, while driving on the freeway with a full van of food, the air conditioning suddenly shut down - even the fan. After seeing so many odyssey having the same problem, I called corporate again to find out whether there's a recall. They actually told me that there is no recall for this problem and I just need to take it to the dealer and pay for the repair myself.
    I began to think Honda is ripping its customers off by selling detective products. My Odyssey has not only air conditioning problem, but also transmission, steering pump and brake problem. My Odyssey is the most expensive and has most problems vehicle that I have ever own.

    I posted about my problem earlier. After finding I needed to replace the transmission, my AC stopped blowing. The AC turned out to be a symptom of a computer problem. After paying big bucks for new transmission I was faced with having to replace the computer for more big money. To save $$$ the computer shop did a Plan B for me and rerouted around faulty circuit to allow AC to blow (full blast only). 24 hrs later the fan went out... Time for a new vehicle!!!

    Must be either a creature of habit or like to subject myself to more hardship, but I actually like the Odyssey when it works...so bought the 2011. At the dealership looking at their warranty, the sales rep warned about "ghosts in the machine" that should be tackled when first evident. Reminded me how the old van for months had issues like rear windows not responding, sliding doors opening on their own, the back light for the odometer not working... little things that I could deal with. Letting these things go without attention could perhaps result in the larger problems I faced later. Lesson learned for me. :sick:

    not to metion the tranny issues. Get rid of the van ASAP......February 2012 Motor Trend Long Test Article 2011 Odyssey Touring Elite, 6 months old, 14999 miles "...we'll have the technicians look at the transmission as well. Over time, shifting has become rough, and occasionally upon acceleration between first and second gears, the transmission seems to be shuddering."

    Hi, I'm having the same issue. Could you please tell us how the problem was resolved for you?

    According to discountacparts.com:
    "Your compressor failed for a reason. The number 1 reason is contamination in the system. Cleaning out this contamination is crucial to ensuring that the new compressor is not also contaminated. Always flush and evacuate before changing parts. Always use A/C system flush solvent. If it is not perfectly clean after the flush and vacuum, we recommend re-flushing the system."

    My Atlanta Honda dealer botched my A/C system repair by initially just installing a new compressor and running the system to note poor performance. Only then did they inspect the accumulator/drier (replacement of this part is REQUIRED by every compressor manufacturer as part of the warranty) and noted it was leaking desiccant balls and other black junk into the system. THEN they decided to flush only the evaporator line and replace the clogged dryer and also the contaminated condensor (the A/C radiator at the front of the car, often difficult to flush). This is noted right on my invoice! The invoice doesn't mention cleaning or replacing the expansion valve nor purging the other line - things any half-trained A/C technician would have done. Obviously, my new compressor now has it's oil flooded with seven years of accumulated black crud. So I just paid $2,000 for a brand new compressor which WILL fail prematurely.

    I have a case open with Honda corporate to see what they can do given that the repair ddn't follow the Honda's - or anyone's - service procedures. You have to watch your dealer closely to ensure they perform the A/C repair correctly. The warranty on the repair will be only 90-days labor / 12 -months parts so, if the new compressor fails again within a year, you get to hassle with them all over again on the labor. After a year, you're just out another $1,500-$1,800.

    Honda responded to my complaint about my A/C system repair. I had faxed them Denso’s warranty on their compressors (requires system purging and dryer replacement or the warranty is immediately void) along with industry articles describing the importance of thoroughly cleaning A/C systems to avoid contaminating a new compressor. I faxed them a copy of the Honda Service Bulletin showing the easy and very inexpensive alternative to the dealer’s suggested $480 power steering pump rebuild to cure a minor noise issue. I explained how the Service Advisor switched from protesting AGAINST additional work that would be wise (but would have required him to come in on his day off OR split his commission with someone else) to pushing unnecessary and over-priced work the next day (once he was resigned to protecting his commission by coming in on his day off, the Service Advisor wanted to make it damned worth his while). I explained how the dealer tried to charge me 8.976111 shop hours (a plugged number they made up) before they backed off their “mistake” and cut the labor charge by 40%.

    Bottom line: Honda said repairing a contaminated A/C system just by replacing one part at a time was “proper”. The attempted over-charges and commission wrangling are solely between me and the dealership. Honda suggested I contact the dealership Service Manager again to see if he can explain what they had previously refused to explain. In a word, Honda offered me NOTHING.

    If you’re looking for Honda dealer service in downtown Atlanta, you’d be wise to go far North (Woodstock, Georgia) or far South (Morrow, Georgia) instead. Even then, ask in advance to insure that your Service Advisor will be working the next day too in case your car needs to stay overnight. If anyone quotes you a price over the phone, get their full name to avoid hassles over service prices and commissions. Better yet, find a small, local shop who works off their reputation and repeat customers instead.
  • I have a Honda Odyssey 2000 when turn on my a/c blow air but the the a/c button not turn on the compressor i thing is end freon but when i try put freon the compressor not activated and the freon not Go trouth i Check the fuse at front and inside and everything are good
