Re: Air Conditioner Always ON
In my haste I missed a private TSB on this. This TSB is between the General and the dealers. No public display of it but according to the General. On startup the HVAC defaults to defrost and that is why the AC comes on at start up. Futher GM reccomends no corrective action be taken because no fix exists and that it is normal operation.
