blower motor wiring question
I've been having sporatic problems with my blower motor not working. With everything in the truck off, and the key in the "on" position, I can hear a light click when I turn on the blower fan, but I don't always turn on the blower. I'm thinking the heater resistor may be failing, but how can I be sure? I don't want to swap that and it turn out that the blower motor isn't working..!!
If the blower were bad, would it sometimes work and other times not work?
