Re: Automotive Heater Fan Switches
I would imagine that you are asking about an older vehicle heater, since there is a big difference between a heater that uses a blower motor resistor, than a system that uses a computer controlled automatic heater system. In an older one with a blower resistor, most of them are wired so that the cur...
