Heater blower motor resistor question
My fan only works in the high position, so I was told it had to be the resistor. I took it out and it was corroded badly but not broken so I cleaned it up and checked continuity. It tested good between all poles so I put it back in. Still no joy. Then looking at the plug I noticed I'm missing a wire. What goes here - ground maybe? There is a corresponding pole on the resistor but I don't have a wire in that spot.
