Hi Gary thanks for responding, I know that the a/c compressor cycles on and off even in the heat mode. this is not the case it runs as if it is in full a/c mode. as far as the doors working it seems as if its working backwards. In full defrost mode no airflow to the windshield as i turn the temp control toward cold i get more airflow to the windshield.
this still dosent explain why I get no air flow from the defroster when the temp switch is in the hot postion I only get air flow when i move the temp control to the cold postion.
