fix - heater fan speed control - fyi, its not the resistor- video

Recommended Posts

thought i needed a new blower resistor for the blower motor as the #3 speed on the dial for the fan control speed  switch wasnt changing from the #2 speed. no brainer, though it was the resistor, changed it out for a ford resistor and to my surprise there was no change in the #3 speed. further diagnose and teardown led to the speed selector switch as the fault, which as far as i know is not available as a replaceable part but instead u need to replace the  heater/ac control head . teardown of the switch led to the fix.

i made a video of the process and repairing of the switch
