Air Conditioning problem
2004 Chevy Avalanche V8 Four Wheel Drive Automatic 64000 miles
I have the 2004 Chevy Avalanche Z71 model. At random the driver side ac turns off and the heater turns on. The passanger side ac stays on but I can not turn the heat off and the ac back on for the driver side. I have to turn the car off and restart it for the ac to kick back on?
The vehicle has electric actuators that control passenger and drivers side temperature, if it is equipped with dual zone AC. Sounds like that is the problem to me. Most likely there will be a code or codes stored in the body computer that would probably pinpoint which actuator is malfunctioning.
