Hello everyone,

I been looking around lots of resistor problems but don't seem to be my problem i think. Yesterday my wife was driving the truck home and the blower motor turned on by its self and now wont turn off. but does turn off when the truck is turned off is there a relay stuck on ?
never really looked in to it yet as i work most days and nights.
thanks for your time.

If the blower turns off with the truck then the relay is working fine.
Your switch is shorted (or wiring to blower resistor) to ground.

 

Exactly. My thought it also the switch since it controls ANY voltage going to the blower resistor and fan motor.
