Just to let everone know I started to have trouble with my ac temps again blowing warm to cool air and now its fixed, will freeze your dodads off now, the service manager at my local dealership found a defective cycle switch that cycles the compressor sometimes it would cycle the compressor not enought or not at all, its located on the side of the silver can by the passenger side firewall (forgot the name of it) he said he has had alot of them come back for this. Just want to pass this on incase other people are having the same problem.

Hey, thanks for the info. I think mine is doing that too. Do you have to open up the system to change the switch? On the older chevy's, there was a schrader valve on the low side pressure switch, Didn't have to drain the system.

No, the service manger didnt even take it back to the garage he changed it right in the service bay took him about 2 minutes just unplugged it and unscrewed it and put the new one on.No system drain or nothing.
