Quick facts

- Fits: 2012-2013 Chevrolet Silverado 1500 and other vehicles
- Condition: New
A worn compressor can show up as warm air from the vents, a noisy or seized clutch pulley, or a clutch that never engages. Before you replace it, rule out a low refrigerant charge, a leak elsewhere in the system and a blown fuse or relay, since any of them can also leave the air warm. A shop can test the system.
