Re: need help with heater blower motor wiring

Red wire gets full time power; Should have originally come from the starter post, thru a fusible link, and up to the cut wire shown in your picture.

Black wire is ground for the motor and the relay. Splice an "EYE" at the end of that wire & screw it to the body.

Blue wire: IIRC ( AKA = I THINK! ) is AC signal from the AC pressure switch. Double check to be sure !


So; connect power and ground, then try to turn on the blower.
