Quick facts

- Fits: 2003-2013 Chevrolet Silverado 2500 and other vehicles
- Condition: Remanufactured
Warm air from the vents, a grinding or squealing noise, or oily residue around the compressor can mean it is wearing out. None of those proves the compressor is at fault; a refrigerant leak elsewhere in the system can also leave the vents warm.
