I have a 08 ltz suburban and started having some issues with the automatic climate control up front. Regardless of the set temp on either driver or passenger side it only blows cold air. Also it will only blow out the vents, will not blow out the floor or defrost. The rear climate control works perfectly. I have tried pulling the HVAC fuses and letting the climate control "re-calibrate" to no avail. Do I have a bad climate control module in the front?

 

I have a 2006 Chevrolet Tahoe, and when we set the temp higher, to get heat out the vents, it's cool air. This is true in the back as well. My wife is getting on my case because I haven't been in too big of a hurry to get this fixed, but with a little one on the way I'd like to get some ideas/answers on how to fix this issue. So, long story short. We raised the dual climate controls to 80 in the front, heart temporarily came out then went cool. The ***** for the back were turned up to 82, was set at the head level, and no hot air, all cool air. Thanks in advance for the help.

 

I have a fully loaded 08 suburban minus the navigation. For some reason my rear climate control button lights are not turning off after I shut off the vehicle and it is causing my battery to die. Everything on it works and not having any other issues. Does anybody have an idea of what might cause this issue?

 

Any answer to the buttons staying illuminated?
