Climate Control Experts, I need your advice

[jlindy]

I have a problem that isn't covered in the FAQ and I did a search as well. I ran the functional check listed in the FAQ by pressing the mode and auto button at the same time while starting the engine. It cycled through 8 modes over and over, but told me nothing. I tried to do the full system test that tells you if sensors are broken by turning on the car, putting the fan to auto and then going one minute all the way cold and one minute all the way hot. Then you press the on/off button and auto at the same time. It did nothing. Now to the problem:

It seems to me like a temperature sensor is not working, but you tell me. On hot days, I treat the auto climate control like a manual to get it to work right. I set the temp to 60 and manually adjust the fan speed to my liking. If I set fan speed to auto, the only temp that engages the fan fully is 60. When I set temp to anything else like 65, it doesn't get half as cold and the fan speed is pretty slow to medium.

Today, on a cooler day, anything but 60 setting was fairly warm if not hot. I was going back and forth between A/C on 60 and off to be comfortable. Is this just a sensor or two? How can this be tested? It seems like all my modes work right directonaly, it is just the A/C knowing when to go hotter or colder.

Any help would be greatly appreciated as I have not read of a problem like this before and couldn't find anything related in FAQ.

Anybody know what the problem could be? Any ideas?

Is the left center vent blowing warm and the right center vent blowing cold. If so, it could be your evaporator. I had this happen just recently and the Acura Technician ran a dye check through the system and detected blue dye leaking at a hole in the evaporator. Hope this is not your case cause it is expensive.

Well - I don't know for sure what it is but one thing I have done (many times lately)

Pull the climate control computer, run through the diagnostics routing, and inspect the board itself for leaking capacitors.

Tony is coming over Monday night to pull his dash for the shift boot - want to join us? I would be happy to show you how.

You know the more I think about it - the more I think we should do it during the daylight hours.

How does Sat. work for everyone? My son has soccer at 9am and we could meet at 11am at my house (or somewhere else) - then off for a fall color drive?

I don't have a lot of room or light and messing with all those small screws would be a pain.

I'll send out a email to see interest.
