Part Description
This A/C air compressor was removed from a 2012 Jeep Grand Cherokee equipped with the 3.6L Pentastar V6 engine. The compressor has been inspected by our parts team and is on the shelf ready to ship. This is a genuine OEM Jeep part, not an aftermarket replacement.
The A/C compressor is the heart of your vehicle’s air conditioning system, pressurizing refrigerant to create cold air. Common failure symptoms include no cold air, unusual noises when A/C is engaged, or visible refrigerant leaks around the compressor. When the compressor fails, replacement is typically the only solution as internal damage cannot be repaired.
