Having problem with my heater controls inside my car but the AC doesn’t work with the controls either. So I’m thinking its a short in the dashboard control panel switches but wanted to make sure before I pull the dash apart.
RESPONSE
I am thinking if it doesn’t blow air out the dash at all on any speed setting that you have a possible blower motor issue (check the “blower fuse” located in the under hood fuse block). Only blows on High speed would be a blower motor resistor issue. Stuck on hot or cold would be an actuator issue. Stuck on defrost/dash/floor would also be an actuator issue. No signal going tot he actuators would be a control panel issue. If you decide to dig into the dash these instructions may help save you a little time.
