Part Description
This A/C air compressor was removed from a 2006 Lincoln Mark LT equipped with the 5.4L 3V engine (production through 12/04/05). The compressor has been thoroughly inspected by our technicians and is currently on the shelf ready for immediate shipment. All mounting brackets and connections are intact and in good working condition.
The A/C compressor is the heart of your vehicle’s air conditioning system, pressurizing refrigerant to create cool air. Common reasons for replacement include internal bearing failure, clutch problems, refrigerant leaks, or electrical issues with the compressor clutch. A failing compressor often produces grinding noises, fails to engage, or causes the A/C system to blow warm air.
