We just recently purchase a used 03 Tahoe LS with the duel climate controls (not automatic). Right now the fan only works on 5. So its all or nothing. I took everything apart to check that the switch was working correctly. I'm guessing that there is a relay or module that actually controls the speeds of the fan. Anyone have any idea what and where this is?

I have a 2003 Z71 w/ 43000 miles. I just noticed a noice from the compressor when I accelerate. After taking it to a local shop, the told me it was the compressor, and gave me a bulletin number from TSB ( is that right?). They suggested I call my local dealer and ask them, because a number of models, according to this bulletin, have been affected. When I spoke w/ the service department at the dealership, they basically told me "too bad", the compressor is coming apart, and there is no help from GM. Has anyone else had this problem? And if so, what was your fix. Thanks

As there are a lot of posts about the Tahoe / Suburban A/C compressor problems I decided to lube mine. I have occasionally had the loud noise from under the hood at engine start-up especially when my Tahoe has been sitting for a few days. From the posts I have learned that this noise comes from the belt tensioner banging around as the compressor tries to lock-up. To prevent any lock-up for lack of lubrication I decided to add one can of compressor lubrication oil in my Tahoe's A/C system. When I added the oil I immediately noticed remarkably big noise reduction when the engine was idling. REALLY BIG difference. I also noticed that the engine runs smoother and guess what, it looks like the gas mileage went up by almost a mile per gallon. --Arrie-- |

Replying to: tidester (Aug 29, 2006 8:54 pm) The thing is it's different from how it used to work, where it would control to the temperature that was set. The dealer simply said that I need a new computer. But to me it seems like a sensor problem, because the computer is still doing everything that it normally does, except backing off when it reaches temperature. It's as if it can no longer sense the cabin temperature correctly. Has anyone had any problem like this, and if so did you figure out how to fix it? Any thoughts would be appreciated. Thanks

| I have a 2001 Tahoe and when I turn the temperature selector knob to full hot that's what I get, even when I turn the temperature selector knob back to full cold -- it still blows full hot. If I turn the motor off and let it sit for about a minute, then start it again, the air will blow cold at the cold setting. But if I nudge the temperature selector to a warmer setting, I get full hot again. Any ideas? | |
