Quick facts
- Part: Four Seasons 5912NK A/C compressor kit
- Fits: 2009-2012 Mercedes-Benz GL450 and other vehicles
- Position: Front
- Condition: New
Warm air from the vents or a grinding noise from the compressor can mean the compressor is worn. Those signs alone do not prove the compressor is at fault, since a refrigerant leak elsewhere in the system can give the same symptom. The system uses a single compressor, so the vehicle takes one kit.
