Question about 2002 GMC Yukon Denali
I have a 2002 GMC Yukon Denali. My A/C and Heating isn't working in the front when turning the knobs on or even turning the settings on high. The rear A/C and heating works fine at any setting. I looked at the fuses under the engine hood and none seem to be shorted out or anything. I even changed the fuses for the air and a/c just to make sure. are there any other fuses I should look at? Please, I need your help!

Did u put in fuel shortly before the light came on? I own 2 service centers & the most common situation with "Check Engine" lights are because the fuel cap wasn't re-installed or not tightened. When you refuel make sure it "clicks" when putting back on. We don't charge for a "Code Reading" but a dealer will, don't go there. Go, like the others suggested. If it is the fuel cap & you re-install it correctly, the light will go off after a short drive. Good Luck. PS-Don't panic when the "Check Engine" light comes on unless it blinks, if that happens don't drive. PSS-RE: Murray's, Auto-Zone.......If it's a "Code" (the reader will give a #) the code book will tell you the problem. PSSS-Some1 please have Troy W's Mommy & Daddy take away his keyboard. Just because you can put together a "Lego" car doesn't make you a master mechanic. You only repeated what we said except you have a "Napoleon" complex against any1 plugging something in to a vehicle. It's the same as plugging in a light @ home. In conjunction with "kinder" nine out of ten time in my experience it usually is the oxygen sensor(s) which would be about right with the year model

it has to do with your air ride suspension best bet is take it to the dealer there is probably a problem with a level sensor. hope this helps you

There is a widespread problem with electrical shorts with the seat warmers. I bought the extended warranty through CarMax and theyy fixed it. Retail repair cost on that would have been $900+. It may be covered by GMC via a recall, but only if you raise enough hell.
