Part Description
This is a used OEM A/C air compressor removed from a 2004 GM Silverado 1500 equipped with a 5.3L engine. The compressor has been thoroughly inspected by our parts specialists and is shelf-ready for immediate shipment. All mounting points, electrical connections, and refrigerant fittings have been verified for proper condition.
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 worn 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.
