Quick facts
- Part: Four Seasons 88963 A/C compressor
- Fits: the 1994-1995 GMC P3500 and other vehicles
- Condition: New
A failing compressor can show up as warm air from the vents, a noisy or slipping clutch, or belt squeal. Warm air alone does not prove the compressor is at fault, because a leak that has emptied the refrigerant gives the same result.
