Part Description
This A/C air compressor was removed from a 2011 Buick Enclave equipped with the 3.6L V6 engine. The compressor has been thoroughly inspected by our technicians and is currently on the shelf ready for immediate shipment.

Common reasons for replacement include internal bearing failure, clutch problems, refrigerant leaks from worn seals, or electrical issues with the compressor clutch. When your A/C stops blowing cold air or makes grinding noises, the compressor is often the culprit requiring replacement.
