ac heater control problem
Have a 40th Annv (93) the heater fan stayed on after shuting down ignition. All efforts to shut it down failed. Finally disconnected it to get battery charged. Is this a replace the whole controller issue or can it be fixed?? JDR
Problem was fan control module, very common problem on GM vehicles. $69 from Ebay.
