Hi
Is there any way to repair a heater vacuum switch? This is the switch that directs the airflow from the heater to the floor, dash or defrost.
TIA

Im not sure on the specifics, but My jimmy was taking a long time switching between floor, dash and defrost mode, and the dealership and to replace vacuum lines.
