You could try a reset by simultaneously pressing mode , front defrost, rear defrost. If that doesn't correct the problem you could have bad actuator sensors, as this system is quite involved in testing procedures I would recommend that you take it to a shop you trust fora system check out. Did you get any kind of warranty when you purchased it?

I have a 2005 GMC Envoy with the Denali package and the 5.3 liter V8, the engine sometimes makes an occasional clunk sound during idle. The RPM's don't move and no other side effects, any idea or history of he 5.3 V8 making this noise and does it mean anything? 2 answers
