Honda Odyssey Heating/Cooling Problems



  • dl6401dl6401 Posts: 1
    My 2000 Odyssey is not blowing cold air. When I turn the a/c on it is blowing, but not getting cold. It has been checked for freon and I have been told that there is no leak. I recently took it to Pep Boys and was told it was the compressor along with hoses,etc,etc. When I asked the guy about the fan not moving he didn't even know what I was talking about, so how do I know he's telling the truth. I know the fan doesn't move when I turn the air on and I don't want to pay$1000 to get this fixed.

    Please help!!!

    Our AC compressor died today at 77,000 miles, we just replaced the power steering pump 3,000 miles ago!
    Honda needs to "beef up" their warranty or people will start looking elsewhere!

    The A/C blows warm air only, and only when fan is on max. Dealer first replaced a $160 A/C "switch". Dealer said this worked 30 seconds, then failed. Dealer now says I need $540 Climate Control unit.

    I'm hugely disappointed in Honda. What is next to go wrong? I have purchased Hondas for the past 20-30 years because of their quality. I'm not sure if my next vehicle will be a Honda.

    I need to remove an air vent for the ceiling interior. One of my kids was plaing with the louvers that direct the air and unsnapped the plastic louvers from the piece they snap into. It can be put back togther if I could figure out how to remove that trim piece from the ceiling. Anyone ever do that?? Thanks

    Dealer is probably clueless... look at forum for replacing the blower motor resistor (transistor assembly) part number 79330-S84-A41... I have a 2004 Odyssey too... with the same symptoms...(The A/C blows warm air only, and only when fan is on max.)

    I bought the part at the dealer today for $75 and replaced it myself... A/C is up and running and fan works at all speeds again.

    My AC has stopped working on my 2010 Odyssey that I purchased 1 month ago. It only has 1400 miles on the car. They are diagnosing the problem but said they can tell the compressor is not engaging. Has anyone else had a problem this early on - I'm very concerned about what this holds for the future.

    My honda air conditioning had stopped working last year and this year finally we got around to taking it to the dealer. I was shocked too at the cost of replacing the compressor. I have been reading the posts and looks like it's a common problem but Honda is not acknowledging it. Should I bother calling them at all or just bite the bullet and get the repairs done ? I'm not a very confrontational person so don't want to call up the dealer or Honda CS and argue about it if there is no luck. Any help will be appreciated.

    Do you have a good relationship with the service dept - meaning are you a regular customer and give them high scores on surveys? If so, ask the service advisor to contact Honda on your behalf for a good will gesture - that you've heard there have been issues with the A/C. No need to be confrontational - just ask. The worst they will say is no.

    If you don't have that relationship - you're probably out of luck.

    Most dealerships have "silver bullets" they can use for good customers. I know I could go to my dealership with my 2000 Ody with 105K if the tranny went and they'd find a way to help me out. I do all my service there and give them high scores. They like me since I'm a profitable customer and they are willing to go the extra mile. Too many folks forget that.

    I am having similar a/c problem - but the defrost won't engage, and can't change the blower location (where the air blows out from) - none of the lights on the a/c dash work, but the fan blows at different speeds (hot air, not cooled). I am thinking maybe it's the transistor based on posts. I found this online and it may help people. Hopefully it's okay to post the video, it's not great quality, but shows you the location of the transistor 79330-s84-A41 Honda, or JA1428 Autozone. Good luck and hopefully this works for me. :sick: I checked all fuses first, and pressure seems okay, actually a bit high. but that shouldn't affect if the a/c blows and the lights, only the compressor I would think.
  • You'd be crazy to try to strike up a "good" relationship with a Honda service department. I mean would you try to strike up a good relationship with the IRS just in case you ever need their? No. When the time comes they will dig through your wallet no matter what you say about them. Just ask how much it costs to replace a cabin air filter on a >05 and after Odyssey, if its anything more than the price of one at autozone (like $10 or $20) then you're paying too much.

    I have a 2005 EX Odyssey that is having consistent A/C problems. Had a relay replaced and it ran well for 2 months and then stopped. There is no leak, ac refrigerant is well above min and below max, new filters, there is a road guard on it to protect the compressor, and fuses all check. The belts seem fine, I will take another look to make sure. The compressor seems to be engaging but no cold air, just hot. Fan is fine, loud but fine. Any thoughts? Alternator? Belts? Clutch? Transistor?

    I have a good napa shop I can take it too, once fixed my ac on an F150 for 1 hour shop labor because the clutch wasn't fully engaging. A washer did the trick. I'm sure the dealer would've replaced the entire thing for $1500. So I trust this shop but if I can try a simple fix today that'd be fantastic.

    BTW, worked for a GMC dealer for 2 years. I have my reasons for not trusting dealers. If you feel as if you can trust a dealer when you buy a car to have shown you the best price on the sticker then you can pay for the dealers maintenance I guess, otherwise, run.
  • Just had my Odyssey repaired due to a stone hitting the condenser. Total cost $781.05.
    I just spoke with Honda Factory Rep, no help there. I just wish they notified me about the problem, I would have gladly paid to have the protective screen around it before the rock incident happened. My vehicle has only 27965 miles on it. I am not very pleased with Honda at this time, I have to wonder what other time bombs they are not telling anyone about. My first experience with Honda and probably my last. So much for listening to Consumer Reports.
    We have a 99 Mountaineer that has never had the A/C even topped off and you can hang meat in it on a hot Summer day.
  • I have the exact same problem on our 09 Odyssey. The AC stopped working twice on two different road trips. Did you get it resolved? I'm taking my car to the dealership in a couple days for them top look at it again because they couldn't figure it out last time.
  • Much the issue here, started out with the front fan not working but rear fan does but not cold air. Now nothing works, not even the LCD display. All fuses are fine but unsure of the relays. I have noticed however that besides the AC issue that the heated seats don't work and the adjustable mirrors don't work. Related? Any suggestions would be appreciated.
  • My Honda Odyssey 2005 has developed the following problem. We normally set the temperature control on 72 and on AUTO, and it has worked fine for 5 years for both heating and cooling. This past summer the air from the front vents started coming out warm. We had to keep turning the temp down to get cold air out the front vents. Now it has to be about 64 before we get cold air do not get warm air in the front vents. The rear vents all blow cold air. All fan speeds and other controls work properly The problem is that the front air is having warm mixed with the cold at to high a temp. So it appears that some temp sensor is not functioning properly in the front. The compressor has been checked and is fine. Any ideas will be appreciated. Thanks

    I had the exact same symptoms. I bought the part for about $40 from a Honda Dealer at, watched the video listed in the #72 reply in this string a couple of times, swapped the new part for the old part in about 15 minutes, and works just like new ! The biggest challenges were finding a Phillips screwdriver short enough to manuever around between the floor of the van and the transistor, and contorting myself into the right position to reach the screws. Otherwise it was a breeze.
  • If I am not mistaken, the problem you have has a recall. I have progressive insurance and there listed with info about my van is recall information as they come up and the wireing harness has been a hot issue with these vans. I'm not that technical so I could also be incorrect, but worth a look into.
  • when the temp is set at between 70.....80 the air out of the vent starts out nice and warm but then after a while cold air starts coming out of the vents which would sort of be ok if it was July and 100 degrees outside! Im wondering if anyone else is having issues like this with their 2011 TIA
  • To: grdanes, Have you checked the temp coming out the front vents and also the rear top vents at the same time. With my temp control set on 72, and it is 90+ outside, my the front vent air temp will be warm while the back top vents will be cold. This indicates that there is a mixing of warm with cold out the front vent. My fan speeds all work properly, front & back.

    The part listed above that some have replaced will fix a fan speed problem, but apparently not a temp control problem. There is a thermister located elsewhere that is hard to get to that may be the problem I have. Your & my problem appear to be the same and different to most of the others mention in this list. :confuse:
  • I'm being driven insane by's 43 windows open, temp set at 75 I've got cold air blowing on me.......pos van :mad: :mad: :mad:
