Was wondering if anybody else has had this problem: when I have the AC/Heat set to "Auto" the fan will blow on, then go off. Blows on, then off. Now when this happens the fan indicator does not change. But the fan will just continue to do this over and over again. If I turn the "Auto" off and just set the fan it will blow consistently. The dealer put the diagnostics on the car and it doesn't show anything. Anybody else have this problem? My guess is it is the sensor that measures the outside temperature that may be at fault.
Please let me know if you have any suggestions.
Thanks.
