My fan switch only works the fan when the a/c lever is moved. I cannot move the heat/defrost lever and operate the fan.
Back of switch has two connections, i think one operates fan as soon as you move the a/c lever and I'm guessing the other connection operates interdependently for the heat/ defrost.
You can't use the a/c fan as the a/c door opens when you move the a/c lever blocking the air flow to the heat/defrost vents.
Hoping that someone out there has an A/C fan switch from a parts car they are not using.
I tried locating a new one from resto dealers, no luck. Also contacted a number of wrecking yards who told me the switch is unique to a/c cars. Any help or direction would be appreciated.

Back of the switch is round. I could not get the two plugs off as they are on real tight and didn't want to damage it. I was planning on trying to get the switch out this week. Shaft goes through the plate and rotates counter clockwise low to high (4 speeds).
Looks like there are 3 prongs on the top plug and 2 on the bottom by the number of wires. Bob.
