What causes vehicle AC compressor failure?
Loss of lubrication is unquestionably the most common cause of compressor failure. A restriction inside the A/C system can also starve the compressor for oil. Oil circulates with the refrigerant, so if the orifice tube or expansion valve is blocked it may cause the compressor to run dry and seize.
What happens when the a / C compressor fails in a car?
When the A/C button is pushed the clutch is engaged, locking the compressor to the pulley, causing it to turn. If the compressor has failed, the A/C system will not work. A compressor that is seized may also contaminate the rest of the A/C system with metal debris. Step 1: Locate the A/C compressor.
How do you change an AC compressor in a car?
This can typically be found on a decal placed somewhere in the engine compartment, or in the vehicle repair manual. Step 2: Rotate the tensioner. Use a socket or wrench to slide the automatic tensioner away from the belt. Whether this is clockwise or counterclockwise depends on the vehicle and belt routing.
How does a car air conditioner compressor work?
All modern compressors utilize a clutch and drive pulley. The pulley is driven off a drive belt whenever the engine is running. When the A/C button is pushed the clutch is engaged, locking the compressor to the pulley, causing it to turn. If the compressor has failed, the A/C system will not work.
When does an AC compressor need to be replaced?
This all depends on if the compressor came apart and sent debris throughout the entire system. If so, either the system will need to be flushed out or all of the components will need to be replaced. The next issue is your car has R12 refrigerant in it and this has to be retrofit to the replacement R134.
