Quick facts

- Fits: the 1993-2002 Cadillac Eldorado and other vehicles
- Condition: New
A clutch that will not engage, grinding or squealing from the compressor, or air that stays warm can mean the compressor is worn. Low refrigerant, a leaking line or a slipping belt can produce these too, so with the engine off, look over the belt and the fittings for oily residue or damage before replacing the compressor.
