Does anyone know if i can buy a new fan switch for heater/vent/defrost assembly? I found one switch for mach 1 with ac but my car is without. Not sure if I can use that or what the difference is.

I do not know for sure but I can give you a one stop place for the answer.
Look up Don Witt at Ohio Mustang Supply. He will be able to give you the answer and tell you what is available and where if he does not personally have one.

Turns out that the switch is good. There's no voltage on the plug. I believe voltage should be on yellow wire. Does anyone know if hot wire for fan switch is directly connected to fuse box? Not sure since it could also be to starter switch.

The last I new you could still buy one from Mustangs Unlimited I thought I needed one last year but found the problem was just a loose fuse. I'd check with them. Good luck.
