#57 of 372 AC Climate control Switch
Apr 24, 2008 (9:21 am)
I have a 2002 Chevy Tahoe. I have noticed that some of the back lights on my dash board switches have went out, but everything still works. ex.. defroster button. Recently when I try turning on the AC it will blink a couple of times then turn back off, most of the time it is when I idle. Sometimes once I get going or at times even as soon as I crank the truck it will turn on itself and work fine. When it is on it blows cold and works fine. Could this be electrical or the AC itself??
#58 of 372 96 Suburban Front and Rear Air Issue
May 05, 2008 (2:32 pm)
Hello, Nice Place ya got going here!
I just bought a 1996 Suburban 4x4 5.7L
The front AC works, but the blower will not work on the "HIGH" setting If i toggle the switch back & forth i can hear a clicking under the passenger dash area when its clicked into high.
the rear AC does NOT work, however when i use the switch i can hear the same clicking noise thru all speeds ( Lo - High) when i toggle the switch.
So, I have a Several questions:
(1) Is This usually a blower motor issue--- or a switch issue ( Both front and Back)
(2) From the clicking sound, is there a blower motor in the back on the passenger side as well?
(3) Are these Jobs easy to access and fix from inside the cabin?
Thanks for your time!
#59 of 372 ac compressor always on
May 07, 2008 (7:18 am)
I have a 2001 suburban. The ac switch seems to work, light comes on when depressed, goes off when pushed. However, the compressor seems to run all of the time regardless of the switch setting. Any ideas? is this normal. I do not have the vent controller set on defrost.

Had a 97 sub (replaced now with an 07), so can help a little.
In regards to (2), the rear unit has it's own set of circuitry, blower, ductwork and sensors. You can find it along the right rear. The bulk of it is in the far back, but ductwork and sensor runs all the way up to the 2nd door on the right. Access it from the far back.
I still have my factory service manuals, so can look up something for you if you have a specific question.

There is a set of high and low freon pressure switches, which control relays, which controls the operations of the a/c compressor clutch.

Thanks for the response. However, I fiddled around some more and found something interesting. The compressor stays on continually (regardless of ac switch position) only when I have the recirculate air selected. The ac switch functions normally when I have the fresh air selected.
#63 of 372 2001 suburban, driver's side rear window not working
May 15, 2008 (4:10 pm)
I can hear a click when I hit the window button from either the driver's door or the affected door. I would normally think this was a motor that needs to be replaced. However, there was a brief period when the window started working, it functioned normally for about two weeks then quit never to work again. I can still here it picking the motor when the switch is depressed. I dont want to waste the money on a motor if I have a short. Any ideas? thanks.
#65 of 372 tahoe climate control problem
May 29, 2008 (4:15 am)
I have a 2002 5.3 liter tahoe. For the past year the rear a/c, heater, and blower ... for no reason will stop working. Then later on ... after the vehicle has been parked and resterted ... the overhead selector switches, for the rear a/c, would begin operating the system again. Then after a few more months, only the front overhead a/c controls would operate the rear a/c, heat, and blower. But as I said earilier, for no apparent reason, the rear blower would stop blowing. Now nether the front or rear, overhead controls will operate the rear a/c, heat. or fan. it's hard to believe that both switch panels are defective. The front passenger a/c, heat, and blower works fine. Any help would be appreciated.
#66 of 372 A/C Problems only when wet
May 30, 2008 (1:08 pm)
I have a 2001 Suburban. The air conditioner works fine, unless the car is wet (after rain or car wash) the light on the dashboard won't light and the A/C won't work. This happens whether the car is idling or moving. Once the vehicle dries off the A/C starts working again. Not sure what is causing this. Any ideas?
