Climate control problem...bad switch??
Posted this over at the HVAC forum but thought I would try it here also. I have a 2001 F150 SCREW 4x4. Last winter the climate control (hot/cold) **** stopped switching between hot and cold.... it would only blow heat. I figured it was a broken blend door and decided to tackle the job this spring. Everything else works like it should.
Well, I have dug into it and the blend door is fine. The actuator motor appears fine also. I replaced the actuator motor and still nothing. I checked the voltage going to the motor and got NOTHING. So my question is, could it be the climate control temperature switch on the back of the climate control panel that is bad?
I have not checked the voltage going into the switch yet but I am at a loss right now. Could the actuator motor get power from somewhere else or does it come from the climate control switch?
