Am I thinking right here:
Since the compressor dosen't run when the a/c is off I think that means that the electromagnetic clutch on the compresser is good.
If the car was drained completely of freon and the compressor still engages we know that the pressure switch must be bad.
I might as well fill it with 152a and dye see if it cools and find my leaks. Drain it again and Replace the A/C seals and the pressure switch.
If I do this how do I know if the proper amount of oil is remaining in the system? It it as simple as removing the fill hole screw and filling it up?
