I have A 1997 Lesabre Limited. The A/C clutch just started making a grinding noise while the car is running. I popped the hood and can see metal shavings on the clutch. If I turn on the defrost and the clutch engages, the noise stops. It works perfectly while the clutch is engaged. So I figure its a bad clutch. I just searched and could not find a souce for just the clutch. It seems I have to buy the whole compressor/clutch. I sure would like to just replace the clutch. Is that doable? If so, where can I buy just the clutch?
