Part Description
This A/C air compressor was removed from a 2006 GM Trucks Silverado 1500 equipped with a 5.3L engine. The compressor has been thoroughly inspected by our experienced technicians and is currently on the shelf ready to ship to your location.
The A/C compressor is the heart of your vehicle’s air conditioning system, pressurizing and circulating refrigerant throughout the system. Common reasons for replacement include internal bearing failure, clutch problems, refrigerant leaks from seals, or electrical issues with the clutch coil. When your A/C stops blowing cold air or makes grinding noises, the compressor is often the culprit.
