My bet is what LittleGreen4x4 said, or perhaps the clutch switch itself. Using a feeler gauge, check the gap between the clutch and disc. A test to see if it's the gap is to start the truck up and turn on the A/C. Using the handle of a hammer or screwdriver, tap the clutch disc and see if it catches and runs. Be quick, and careful doing this!

I have not yet. I am ashamed, I asked for help and have not been able to give you guys feed back yet. Between unloading barn lumber, kids soccer and work time is a premiun right now.
I apologize but I will try to get to it tonight after soccer or tomorrow evening.

In the mean time it is the 2/70 a/c mod. LOL

Good Luck

What happens is it loses connection due to wear on the plug itself.

OK you and Cody (Rubberduck) nailed this one.

I finally got a chance to get under the hood before dark. I cranked it up and turned on the a/c. I reached up and hit the wires and the plug on the back side of the compressor. Voila the compressor kicked on when i pulle dthe wires forward.
I removed the plug and disassembled it completely. Cleaned the male contacts and tightened up the female ones, then reassembled and it is working like new. 12 year old clutch, freon and all. ICE COLD!!!

Thanks guys for all the suggestions and help.

As some of you know I love to give out reps. Here they come guys.

That is awesome. I have never touched my AC either. It is amazing. This is one the things Ford did right.

Glad to hear about the simple repair, Neal.

Ford did put an awesome AC in our rigs. Mine is going on 14 years old, it's still ICE cold and has never been serviced. My 86 Bronco still has the original R-12 system and works pretty well, although the original compressor is starting to go. My 01 Stang has a really junky compressor. It leaks between the 2 compressor halves and needs a charge every couple of years. Next time it needs one the compressor is getting tossed.
