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.

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?
