The car has been getting hot while idle also. Should the fan run all the time? Where do the leads go to on the clutch?

See if you have voltage at socket #5 of the Klima. If you do, then jump sockets 5 and 7. The compressor clutch should engage. If it does not engage, then either the clutch is NG or your plug at the clutch is NG. I'm inclined to believe that it's the latter because sometimes you have the clutch engaging and sometimes you don't.
Did you ever unplug the clutch and check out the plug?. It's in a bad area and probably has not been checked in 20 years. You need continuity between the clutch and socket #7 of the Klima.
I don't understand the phrase "The CCU was cutting on and off by itself"???
