I own a 2004 Envoy xl 6 cyl 2 wheel Drive The problem is the rear A/C unit. Front unit is fine. All functions work and blows cold at 42/45 degrees. The rear when you turn the system on usually does nothing but every so often will come to life for anything from 5 seconds to a 1-2 min. then shuts off. Following suggestions I replaced the small control sw. on the console as it was bound up. No change. I then got the fan module for the rear thinking is was bad but noticed that when connecting the old one AND new one back up will get the same momentary results. (P.S. When it works all rear components work.) I did notice that the new one being out of the car the new module got surprisingly very hot. I disconnected and put it away for now as the module in the truck appears good.
Is there a way to check out the electrical side of this? In the console is the rear controller: Temp, Vents and Fan Speed. Also is a module with a data link to the main A/C control up front. ----- HELP!!----- Any Suggestions PLEASE!
