How does a car air conditioner compressor work?
An AC system has many components: compressor, condenser, receiver dryer, evaporator, and hoses. 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.
How do you remove an AC compressor from a car?
Remove the negative battery cable from its post. Remove the bolt at the compressor that secures the refrigerant lines and inspect the lines carefully for dirt or signs of wear. Disconnect the compressor’s electrical connections. Remove the compressor’s mounting bolts and pull the unit from the vehicle.
