Volkswagen Passat AC Compressor Clutch

A functional air conditioner in your Volkswagen Passat is essential for summertime comfort. While you can always roll down your windows to catch a breeze, humidity and precipitation can eliminate that option quickly. Fortunately, you can find everything you need to repair your AC including bands, pulleys, bearings, refrigerant, compressor clutches, and more from a variety of trusted manufacturers.

In all models of vehicle, the compressor clutch is an essential component of your air conditioning assembly. It is the part that engages and disengages the AC compressor, which applies pressure to a refrigerant gas and circulates it to chill the air in the evaporation coil. Without this part, the AC would never turn on, but just as importantly, it would never turn off. Its important that your system is allowed to rest, which preserves the longevity of your other parts and saves gas mileage in the long run.

There is only one kind of compressor clutch for your Volkswagen Passat: the electromagnetic type. There are no special functions that this part can perform, so while you have flexibility when choosing what brand your clutch comes from, theyll all perform similarly.

Naturally, you may be concerned about the condition of a fresh replacement, especially if it was refurbished. However, while this part is usually very reliable, there are a few signs that you can listen for that indicate your new compressor clutch is working properly:

• When you first turn on the AC, there should be a soft thump or click from the engine, indicating that the compressor clutch has engaged.
• While the AC runs, there should be a gentle humming or no apparent sound, which indicates that the compressor has properly switched all the way on.
• Every 10 or so minutes, the thump or click should trip again, alternating between on and off states and allowing the system to rest on an interval.
• In tune with these intervals, the air should be cold, but not frigid.

If you believe that your clutch is ready for a replacement, there are two benefits to doing so. First, it will preserve the other parts in your AC. An improperly working compressor clutch can put additional stress on the other parts. Second, it could save on fuel. If a compressor clutch is stuck in the on position it will continuously draw unnecessary power and as a result, it uses more fuel.
