CLIMATE SYSTEM CONTINUES UNTIL THE BATTERY IS DEAD
2004 GMC Envoy

Our 2004 envoy SLT has an automatic climate control system. Problem is that when the car is turned off and key removed, the fan for the climate system continues to run until the battery dies. Have tried all manipulations for the auto and off functions but the system continues to run.
The problem is intermittent and you can only turn off the fan by disconnecting the battery.
You have to take this that knows auto temp control this can be a screw up in the control panel or a bad ground. These things are a pain to diagnose because there just aren't that many of them and all of the ocntrols that they have to make them work.
