Quick facts
- Part: Four Seasons 88931 A/C compressor
- Fits: the 1999-2002 Chevrolet C1500 and other vehicles
- Condition: New
Warm air from the vents, a clutch that will not engage or oil residue on the compressor body can mean the compressor is failing, but other parts of the A/C system could be behind those signs. With the engine off, look over the compressor body, fittings and belt for oil film or damage, and leave pressure tests to a shop with gauges. If the compressor is the cause, this unit replaces it.
