63/64 Air conditioning

[64V-K7]

Anyone have a wiring diagram for 63/64 factory A/C.

I don't have a wiring diagram, but I do have an outfit off of a '64, although nearly all AC's are about the same. I'll have to dig it up and look at the wires to be sure, but if memory serves me correctly, there's only about three wires from the evaporator unit with loose ends. One goes to the ignition switch and I think it had a fuse holder in it. There'll be a ground wire which I think came out of the fan motor and the third, long wire goes to the electric clutch on the compressor. If you need, I'll try to remember to check it out tomorrow but that's all there should be.

Thanks John,

I hesitated to ask, as they all work the same way. I didn't think about the ground wire though and that's most likely the problem.

I checked this morning and I was wrong, there's only two wires, the 12V positive and the clutch. The fan motor is grounded to the unit itself which then has to ground itself through the dash framework. I think I'd feel better with attaching a ground wire to the grounded terminal on the unit and then connecting that wire to another ground source.
