Good to know, Al. I wouldnt mind gambling on a switch- know where it might be? And once I find it any way to test it with an ohmmeter?

I don't know its specs and how to test it, unfortunately.

Can you see a wire going to the compressor's back and ending in some kind of probe? That probe is the thermal switch i'm speaking about.

I see a wire going from the clutch to compressor, then going to the FRONT of the comp, clipped onto a clip which is secured to front of car, right behind front frame, next to fans. But it appears to be only a connector, no probe. Maybe I will have to take it in somewhere.

Im ordering a new comp. Meanwhile, I am not using the ac as more damage can occur.

Your call. Good preventive course of action when dealing with an old car anyway. Compressors do eventually get old and worn no matter how you treat them. It simply gets to a point where you're beating a dead horse. That is, you finally manage to get a compressor to work right, but you also notice that it's taking a little too much time and rpm to get the air really cold, and it's also noisier than it used to be.
