If there is sludge or debris, the hoses, evaporator, and condenser should be flushed to get rid of the contaminants.
A compressor may also fail if there is sludge or debris in the air conditioning system. If the seals no longer hold, you will need a new compressor, as the seals cannot be replaced. The compressor may start leaking refrigerant and/or the AC oil. It is also common for the seals in the AC compressor to go bad. Sometimes replacing the entire compressor with a remanufactured one can be cheaper than replacing an individual clutch or bearings. If the bearing or clutch have failed, it is recommended that the compressor be replaced. The clutch can burn or the bearing can fail. The clutch is driven by a drive/serpentine belt, which engages the compressor when you switch on the AC. Consequently, it is a requirement to replace the orifice tube and the receiver dryer when replacing the compressor since some of the debris may have ended up there.įor an AC compressor to work, it needs a clutch, bearing, and an electrical connector. It is common for the internal parts of the compressor to come apart and disperse metallic debris throughout the system. These internal parts can fail, causing the AC compressor to stop working. The AC compressor has several moving parts (including pistons and valves).
The compressor, the “heart” of the car’s air conditioning system works like a pump taking refrigerant, (R-12 in older cars, R-134a in 1995 and newer cars) and pressurizing it, passing it along to the evaporator. Plus when you push the A/C button, this is an input to the BCM - body control.
