Replacing The AC Compressor Clutch. Re: AC Compressor replacement Refrigerant can still remain in a system but below a pressure too low to run, that is detected by a pressure switch sending a signal to the pcm to disable power to the compressor clutch, preventing compressor operation. Does the system have to be recharged to make the clutch engage. If your AC compressor clutch air gap is wrong, the compressor compressor clutch air gapclutch won’t engage or may engage but slip. We do that in several ways.
