I'm misssing the resistor on my 68. It is mounted right behind the relay on the top of the a/c box. There are 4 or 5 prongs sticking up in this spot. Does the resistor mount directly onto these prongs? Does anyone stock this part or will I have to find one at the junkyard? Also what years are interchangable? Thanks in advance.

Those prongs ARE the resister, it hangs inside the box to keep it cool

I'll have to check it out better tonight. If it is in place then I'm just missing the part of the harness that plugs in there. I'll investigate a little further. Thanks.

Well, after further inspection, it appears as though I'm missing a part of the wiring harness that inludes that connection. It appears like there is a similar two-prong resistor on the fender side of the air box as well and this part of the harness is also gone. I'm thinking that the previous owner that disconnected the a/c got rid of the wiring to clean up the engine bay but didn't realize that by doing so the blower would only work on high speed. My back-up lights don't work as well so, I guess I'll start unwrapping the looms and follow it backward until I find where the wiring was loped off. Thanks guys for the help.

sics, the a/c wiring harness was completely separate from the main engine harness. It comes through a hole on the upper pass side of the firewall. They are not even taped together.

The orange wire in the main engine harness provides high blower speed (which you have), and it is the ONLY wire that A/C shares with a non-a/c system.

Maybe MarkC will chime in on this, he's a bit of an expert on the A/C system.

Thanks Jim, I'll look for that hole and see if I can find where that harness was terminated. The relay has two red wires going to it so I believe the wiring has been partially re-done by someone in the past.

You can't miss the engine side wiring harness, it comes thru a 1 1/2" diameter hole in the firewall just inboard of the A/C suitcase about 3" above the passenger side head. There is a rubber grommet there about the size of a golf ball with about 6 or 8 wires in it.

The two prongs on the fender side of the suitcase are the low temperature cut off switch which keeps you compressor clutch from being engaged when the air temperature is below 39 degrees (I think), to keep your evaporator from freezing up. It is inline with a switch on the A/C control lever inside the car that provides power to the clutch when the lever is in A/C or Bi-level.

I don't think I have that many wires comming thru and after checking under the dash, it looks like part of the wiring was removed before entering the firewall. I'll try to sort it out more this weekend as I've been pretty busy this week finishing up my new interior. Thanks for the info Mark.

You can get that whole harness for the a/c for under a hundred. Are you going to make it cool again?

Haven't decided yet. May get the harness anyhow just to eliminate the patchwork job.
