I never drive in heavy traffic & I don't think the fan ever turns on anyway...
Plus I'm going to be selling the Indy too.

What kind of lame brain idea do you have?

Thanks Paul. I have found a couple, but all are in need of paint, too. And are much farther away.
I'll keep you in mind. I may just hang up my lame brain idea, anyway.

Especially for the Duke, it would be wise to get Rodney's 210° fan switch.

I have several rear clips & decklids but none that you wouldn't have to paint. I also have most parts for a fastback conversion.
I don't have any taillights. I sold all I had years ago for $20 each. Now I need a left one for the Indy... (but I'm broke).

Got the fan working. Finally found in one of my several books that told me where the fan relay was. Pro tip - it's in the front compartment under the left headlight. Would have been nice to know that when I had the headlight assy. out...
Anyway swapped out the relay from the parts car & viola! Fan now comes on when I turn on the AC. Haven't warmed it up enough to test the temp switch but I'm not worried about that.
Thanks everyone for all the help.

Well, it was a beautiful day to ride up to Franklin, NC and back this morning.  You should have come with me.

I could have rebuilt it for someone.  I did a lot of them.  The screws and nuts usually came with most of the kits.  I sometimes used nylock nuts on my screws and other times I used the star washer nuts that were supplied.

The coolant fan switch is on the front side of the engine just below the thermostat housing and points at the driver's back.  The gauge switch is next to the thermostat housing and stands straight up.  The coolant temperature switch (ECM injector control) is the one that screws into the thermostat housing. 

When using a meter or test light on the circuit at the fan motor, the fan switch circuit has to be closed or grounded at the engine in order to complete the circuit.  If your harness connection is between the ballast and motor, it may be that the ballast is bad.  I don't know if the ground runs through the hvac control or not, but probably the hot wire will. 

I found this 84 diagram on Pennocks.  Maybe it will help.

Well I mucked with it again today. There are three temp sensors - two on the head & one on the t-stat housing. All of them have two wires to them. Nothing I do with any of them makes the fan run. I did ground the test light & there is no power to either of the fan wires.
I did get the l. headlight to go up & down today by swapping the motor. The motor I put in (off of the parts car) had screws in the housing. I bet you rebuilt that one, didn't you Charlie?
Thanks,

If you're testing the circuit by using both wires at the fan, that may not work due to the ground coming through a closed sensor at high temperature.  It would have to be grounded to the chassis somewhere up front.

84s have a two speed fan. Those may both be "hot" wires, for the two speeds (unless one of them is obviously a ground). I would check between each wire, and ground. Of course, I could be missing something, since I'm not there, looking at it.
