Honda Odyssey Heating/Cooling Problems

ib9623ib9623 Posts: 2
i have an 02 odyssey , there is no temperature control on ac
or heat mode,unless you turn the temp control to the max ,then it will turn on , any other setting i get no air.
i checked freon...and i have good pressure,also jumped out
the freon low pressure cut-out switch......that didn't help.
i want to check the inside and outside temp. sensors, but
i can't find them....does anyone know where these sensors are located ??....can anyone help????

    the 02 doesn't have an automatic setting control by temperature does it? if it doesn't, i would suspect there is no sensors.

    yes , you can set a digital readout from 60 to 90 degrees

    ahhh, ok, thanks.

    perhaps your problem is related either to the relay assembly (see items marked 2) or it is the "thermistor" (see the item marked 19) in the following exploded view diagram:
    http://www.hondaautomotiveparts.com/auto/jsp/mws/prddisplay.jsp?inputstate=5&cat- - - - cgry1=Odyssey&catcgry2=2002&catcgry3=5DR+EXL+LEATHER+RES&catcgry4=KA5AT&catcgry5- - - - =A%2FC+++++COOLING+UNIT

    one thing you may wish to try is determine if the relays in that diagram are currently well seated in their sockets. if they've vibrated loose, that may be an issue. same is true for checking the connection on the thermistor that is currently in there.

    did you try googling or looking at a Helm's repair manual, maybe speaking with an independant specializing in Hondas?

    good luck.

    Hello,

    A couple days ago the climate controls froze up and won't respond. The manual controls still work on the navigation screen but the Auto assembly right above it doesn't work at all. Thanks

    The FRONT control Assembly for the rear AC/Heat just stopped working. The dials spins and if I'm lucky I get high AC other times nothing.

    I found the part,#14

    Anyone know how complex it is to replace? Can I do it myself?

    I have a 2006 Odyssey with 8000 miles on it. When I turn off the air conditioner and run the system on Fresh Air Mode only, I get this really bad musky smell from the vents. With the AC on there is no smell at all. Is this normal and does anybody have the same problem?
  • What ended up being the problem. I'm having the exact same problem with my 2002 Odyssey.

    Thanks for any information.

    I never did anything about it. AC is always on in the back, so in the summer it isnt a problem. Let me know what you do. I'm tempted to do it myself, but i'm worried how hard it will be to get the dash panel off.
  • I'm not getting air in front or rear. I've had it checked out with and independent that had to eat $450 for a new climate control module that didn't fix the problem. Symptoms are identical to yours. I'm certain that the dash doesn't have to be removed to replace the climate control module. The independent had the old one out and the new one installed within an hour.

    Hello ,
    I have a brand new 07 odysset EX-L RES and NAVI.
    I understand that the passenger and driver can have different temperature setting which is regulated automatically. Everyone in the back will have to manually set temperatures which is not automatic.

    But in Page 215 of the manual it says

    "On EX and EX-L models:
    When the rear passenger’s zone is turned on using the REAR button on the front control panel, the rear passenger compartment temperature is selected based on the driver’s
    temperature setting."

    Does this mean that rear passenger temperature can also be automatically regulated, even though it is set to the temperature of the driver?

    I thougth you could not regulate rear compartment temperature automatically.

    Thanks

    Yes it's correct you can manually set the temperature and fan setting for the rear people from the driver side of the climate control system. What you can't do is use the automatic climate system(which automatically controls fan settings) for the back people. Minor issue in my opinion. I like to manually adjust things anyway.

    I just had a hitch fitted at a Honda dealer. Just the 300$ Honda hitch for a bike rack - no added cooler etc or wiring. It is hot and humid in Chicago today - reading 90 degrees on the bank signs and our thermometer etc., but on the van's readout it says 78 degrees. Would they have switched off the A/c etc to fit the hitch ?

    Since this is a 2007, bought in May from the dealer - is this something that they will rectify regardless of how it was caused without charge?

    Thanks,
    Jahlimey

    Did you every look into changing the relays? My 02 Honda started having the same problem a couple nights ago.
  • Below is from Odyclub.com. Replacing the transistor fixed the problem. Took me about 10 minutes of time and $60.00

    My 2000-EX was doing the same exact thing. Only high fan. Rough noise. No compressor operation. Warm air only.

    I found this forum. Did some reading. And, decided to change the transistor. Did some calling and surfing for the part. The dealer quoted me $60ish over the phone, but dropped it to $45ish when I went to buy it. $45 is comparable to the $38+ from places like Majestic Honda once you’ve factored in the handling and shipping charges. Anyway - It was $52 and some change out the door. I mentioned my symptoms to the parts guy at the dealership. He said he’d heard of all this before.
    I made the comment (jokingly) that I may be back for another part (I think the fan switch relay is mentioned in these posts as well.) if this transistor didn’t fix it. He laughed and said something to the effect of “I think you have the right part for this fix...” He was right.

    The hardest part of the replacement is getting into position to do the work. The unit is located behind (towards the front of the van) the fan blower motor. I pulled the fan out to make getting to the transistor easier, and because I figured it could use a cleaning anyway. It did. Three screws hold the fan in. And three screws hold the transistor unit in. Nothing special about it other than the fan screws being socket or torx drive. The whole job took less than an hour.

    I will note that the new transistor unit does not look exactly like the original in that it has more of what look like cooling fins on it. (Mine does, anyway.)

    After the replacement of the transistor unit. My system works factory new.

    I too, owe these guys quite the THANK YOU !!
    I hate to think of the cost of taking the van to the dealer (or any repair shop), handing them the keys and saying fix the A/C system. Ouch !!

    ps - Please let us know how your story turns out.
  • When using a/c fan hums.The higher the blower speed the higher the hum.
  • Own a 2007 Odyssey Touring w/out navigation. This weekend the van was a little warm inside so I went to put the climate control on auto and set the temp to 68 degrees, just to cool the van down. All 3 controls were set the same. All I got out of the driver's side vent and center stack driver's side vent was really hot air. All the other vents were cool. I turned it down to 65 and still the same thing. The only way I could get those vents to push cool air was to turn the temp all the way to the low position. Is this normal? I know the outside them was around 60 degrees but I would I have never experienced this before.
  • We may be experiencing the same problem. At 35,500 miles, the system on our 2004 Odyssey began blowing only hot air in the front unit (during the heat of the Summer, no less). We've taken the vehicle into the dealership 3 times and they still can't fix the problem. The first two times, they claimed they couldn't recreate the problem and the third time they replaced what they call the "air max motor." It is now Winter and the air is either extremely hot or extremely cold, depending on whether you set the thermostat on 90 degrees or 60 degrees. Any thermostat setting in between will not change the current extreme (hot or cold).

    Please let me know if this is the same problem you experienced and whether the transistor that you refer to is different than the air max motor. We are extremely frustrated and appreciate any helpful responses on this one.

    Thanks to everyone in advance.

    How do you get the glove box out to get to the cabin filter?
