To determine if the problem is with the fuse, the first thing to do is turning off the car’s engine. These include low or excess refrigerant and insufficient oil. There are three reasons why the compressor clutch does not engage, especially if the sensor detects them. Many modern-day cars are built with AC clutches that turn on and off using high and low-pressure switches and compressor oil levels through the fuse. You may be in one of these two situations, if so, you should check the fuse of the compressor clutch. Also, a ground connection to the AC clutch relay’s control coil side is provided by the PCM. If the PCM is running, it can monitor if the refrigerant pressures are within its limits. Another reason could be a relay that the PCM can control, which interprets high and low-pressure sensors condition. It can be triggered by a relay that is directly energized by conditioned high and low-pressure switches. There are many ways for AC compressor clutches to receive power. It could also be of poor ground or a low-pressure lockout. It could be because of a blown fuse, a bad clutch coil, or an open on the wire to the clutch coil. There are many reasons why an AC clutch does not engage. Common reasons why the AC clutch doesn’t engage It’s important to take this issue seriously because an AC compressor failure is almost always related to the engine. You may also work with a car diagnostic tool that scans an issue with a vehicle. Here is a useful tip: If you’re not confident to do the examination yourself, it is best to work with a car expert. If the only rotating part is the pulley, then the clutch fails to run.Make sure that the clutch and the pulley is spinning simultaneously.Look closely and observe the front part of your clutch.Turn the AC controls to maximum air conditioning.Try checking if the clutch is in good condition by applying these steps: However, if the clutch does not connect with the compressor, the compressor will not work and the air conditioning system will fail to cool the car.
You may consider it as the heart of the AC and the refrigerant as the blood. Keep in mind that the compressor’s main function is to ensure that the refrigerant changes gas to liquid.

How to check whether your AC clutch is working This gives power to the pump rotor that keeps the compressor running. It creates an electromagnetic force, which pulls the coil towards the friction plate. Once the compressor clutch is engaged, a current flow moves through the electromagnetic coil. However, most car AC systems now use an electromagnetic clutch piece that engages the compressor to spin the air conditioning unit.Īn AC compressor clutch is made up of a friction plate situated next to an electromagnetic coil. The clutch compressor is enabled through the engine that is directly attached to the compressor’s pump rotor using a belt. Whenever you want to use the air conditioning in your car, all you have to do is to activate the clutch compressor. Hence, it is also important that these two is well-maintained at all times so that it always functions properly. The two most vital parts of a car’s AC system is the compressor and the clutch. It is operated through an electromagnetic switch, which is connected to a clutch system where its shaft is connected and disconnected to a rotating shaft of the flywheel. The AC compressor is empowered by the flywheel of a car’s engine. What is the AC clutch and how does it work?
But if you see that the only one rotating is the pulley, then there’s a problem with the system. If the pulley and the clutch are both spinning it shows that the clutch is engaged with the pulley correctly. Check the front of the compressor clutch.

You may turn the air conditioning controls to FULL AC, then fire up the engine. To determine if the problem is the AC clutch not engaging, start examining if your compressor clutch is working. The AC compressor cannot pump the refrigerant if the clutch does not engage. What you can do if your AC clutch won’t engageĪC clutch not engaging?
