2003 cadillac deville air problem


Recommended Posts


It could be the blower motor, or perhaps a connector to the blower motor. Try turning on the rear-seat blower motor before you turn on the key. If it comes on but the main A/C blower does not, then it probably is the blower motor or its wiring.

The first thing you should do in trying to figure this out is to run the OBD codes, write them down, and post them here.
