Ford Aerostar AC Compressor Clutch
The Ford Aerostar van compressor clutch is a vital component of the air-conditioning system. Its function is to control the speed of the compressor. A fully operational system aids in keeping the Aerostar cabin comfortable for the driver and passengers.
Why is the A/C compressor clutch not switching on?There are several reasons why it may not engage. There may be a wire that is open internally, a blown fuse, or a low-pressure lockout. Other causes include a bad coil or poorly placed ground wire. These possible causes will require further investigation. On the other hand, if the unit is not turning off, it is most likely because the switch has failed. This failure can cause a buildup of refrigerant and freezing of the line. In this instance, you must replace it.
What comes in a Ford A/C compressor clutch kit?The kit includes the belt pulley, coil, snap rings, clutch, and installation hardware. These are all instrumental in replacing the nonworking or worn part.
What are signs of problems with the vehicle compressor clutch?These Ford parts work within the AC to control the pressure and amount of refrigerant that enters the car’s evaporator. A problem can result in damage to the evaporator, compressor or other parts of the Aerostar air-conditioning and electrical systems. If the evaporator freezes up, or the air conditioner begins blowing warm or hot air, it may be necessary to service the vehicle or replace the clutch.
