Default 84 No AC or Cooling Fan

Hi, on my 84 i am having troubles with the AC and the cooling fan on the radiator. The AC is charged but the compressor wont come on unless it is jumped directly to the battery. Also the radiator fan won't come on. I tested both the fan and the relay and they are both good. The fan fuse blows if the car gets hot enough for it to do so. I took the controls out of the dash and cleaned them and nothing changed. Could they be bad? I also tried grounding the cooling fan sensor wire to get it to come on and it immediately blew the fuse.

Batee.com has hvac information that can be downloaded. If fan comes on then fuse fails I would suspect motor needs replaced
