#30 of 100 Re: Chevrolet Suburban & Tahoe: A/C - Climate Control Questions [tidester] by watrpro Jul 22, 2007 (8:12 pm)
Replying to: tidester (Aug 29, 2006 9:54 pm) I have a 1995 Surbaban that only blows air from the defrost. The A/C stopped working the next day. I checked the freon level and it was ok. I also checked the compressor and it worked ok when I sent 12v direstly to it. What can I check next. The a/c button on the dash seems to flicker but nothing happens.

Replying to: watrpro (Jul 22, 2007 8:12 pm) Check the thermistor above the passenger footwell...you have to remove the shield, and then take out the fan...inside is a 2 or 3 paneled heat sink looking part that measures the temp of the air going to the cabin, and thus meters the fan speed. Mine failed (only defrost worked, manual or auto control failed), and it took a $200 trip to the shop to find out that the thermistor fails on quite a few suburbans because of poor QC. The part is under a hundred bucks (from the dealer)...replacing it is as easy as unplugging it and putting the new one in. Hope this helps. Replies to this message: watrpro (Jul 23, 2007 7:34 pm)

Replying to: rgj1960 (Jul 15, 2007 8:22 am) I had a 1999 Tahoe that did that. It was a deformed rubber gasket on the ambulance style doors as a result of a poor manufacturing process. Take a close look at the gasket around the doors and see if any are is crimped as a result of the improper application of glue from the factory.

Replying to: mickgz28 (Feb 09, 2007 7:43 am) Yeah, that's nice. Next time you might want to give Rock Auto a look see (http://www.rockauto.com). They could have sent you the same part for $40.36, shipping included.
#36 of 100 Rear AC blower died by snowman77 Aug 10, 2007 (8:04 pm)
My rear AC blower on a 2002 Tahoe Z71 just stopped working. The front unit works fine. I have checked all the fuses and they are all good. Any ideas what to check next before heading to the dealer?
#37 of 100 97 tahoe ac problem by crash101 Aug 13, 2007 (9:48 am)
tahoe Air Conditioning Problem Vehicle: 1997chevy tahoe 4x4, 5.7L (350)   Problem: When I acquired this used vehicle, I noticed the air conditioning wasn't fully charged and it was blowing luke-cold air from the vents. Everything was working fine and operational, aside from the fact that the air was not very cold). I stopped using the a/c because it wasn't that hot outside, but before I ever had a chance to get the a/c serviced, something must've failed in the system. Now, all that works is just the actual fan motor. I always left the position on the '  (all the way to the left), and now it's stuck that way and only blows air from the floor vents. Even when you try to turn the dial to get the air off of the floor vents, the air continues to blow from the floor vents when the blower motor is turned on, regardless of the position of the selector. Also, the actual A/C button does not work (the light does not illuminate and the compressor does not kick-on anymore...same problem with the other 'air circulation button').
