wwilme Posted August 21, 2005 Report Share Posted August 21, 2005 Our '93 850 GLT has been sitting for 5 months unused. The battery was completely dead, but the car started right up with a jump start. Everything appears to work fine after a short test drive except for the A/C - heat. There are no lights below the recirc air or A/C switches and the fan control appears to be dead. Essentually there is no climate control in the car. I checked the fuses under the hood (fine) and checked that the compressor had not frozen up (turns freely). According to the Haynes manual, the little lights below the switches should flash to indicate a problem. They did not. I tried to check to see if any faults were indicated by the diagnostic unit under the hood as described, but the red light just stayed lit the entire time the ignition was on - there were no flash to indicate a fault. Any one have any ideas short of tearing the ECC control unit out? Please let me know! thanks. Link to comment Share on other sites More sharing options...

RWagin Posted September 2, 2005 Report Share Posted September 2, 2005 I would take the ECC unit out and make sure all the connections are secure, be careful handling the ECC unit. I'd take the radio out also assuming you have the CODE. Link to comment Share on other sites More sharing options...
