I have a '92 Corolla and the A/C clutch has stopped engaging. I turn on the A/C and the engine revs up, telling me that the refrigerant is intact, but nothing from the clutch. I jumped directly from the battery to the clutch with no results. My question is how can I determine if the compressor went bad and took the clutch with it, or can I just replace the clutch? It has R12 freon and I'd really rather not mess with the compressor if I don't have to!

Thanks for any input!
