Warm air from the vents, a noisy compressor or a clutch that stays disengaged can mean the compressor is worn or failing. Before you replace it, rule out low refrigerant, a leak elsewhere in the system, a blown fuse or relay and a worn belt, since each can leave the air warm too.

The vehicles it fits include the 1988-1993 Pontiac LeMans, the 1986-1991 Buick Skylark and the 1988-1991 Oldsmobile Cutlass Calais.
