Part Description
This OEM A/C air compressor was removed from a 2011 GM Trucks Sierra 1500 equipped with a 5.3L engine. The compressor has been thoroughly inspected by our certified technicians and is currently on the shelf ready for immediate shipment. All mounting points and electrical connections are intact and in good working 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.
