sporadic heater/defrost switch- help
trevormares posted a topic in Trouble Shooting / General Engine
Hey Everyone, My heater blower/defrost switch is working sporadically, and with no rhyme or reason that I can tell. They will work and I can have the car parked, turn it off then immediately on again and then they won't work. Only thought I have is they aren't getting enough power. I think this cuz I've seen the defrost switch light almost go out, but a quick rev brings it back up again. Maybe change the a alternator? Any thoughts? Thanks 71, 240z
