If the clutch is not engaged, only a click can be heard.Īlso, look at the pulley. You should also hear the compressor as it runs. When you put your hand on the compressor, you should feel a vibration. For example, feel if the clutch is engaged. You can also use your senses to better diagnose the compressor clutch. If you don't see a surge, something is wrong with the AC compressor, preventing it from turning on. You should see an increase when the system is first turned on. To check this problem, you need to pay close attention to your car's tachometer. If the air conditioning compressor stops working, there may be a problem with the clutch. KEEP READING: Testing the AC compressor clutch The purpose of the low pressure switch is to shut off power to the compressor clutch without enough pressure. On the other hand, without enough refrigerant, a malfunction may occur.

If the system is overloaded, the high pressure switch disables clutch operation. The only solution would be to repair or replace what is damaged.įor the air conditioning system to work properly, the refrigerant must be filled to a certain level.

If any of the wires or connectors are cracked or damaged, the signal may not reach the compressor. Signals are sent through these connections to activate the compressor. Your car's air conditioning system is made up of several plugs and cables. If any of these switches fail, the air conditioning compressor may not turn on. A malfunction in one of the switches could cause it to remain disengaged.Īmong the most notable possibilities are Low or high pressure switch, as well as evaporator temperature sensors. Several switches are needed to activate the compressor clutch. Make sure the amperage matches what it burst. In that case, you would have to replace the fuse with a similar one. If the fuse blows, the compressor will not be able to get the energy it needs to run. The compressor clutch may not engage for reasons other than a malfunction. Reasons Why AC Compressor Clutch Does Not Engage Depending on the severity of the leak, cooling performance will be degraded. If the clutch is not working properly, the front seal could leak.Īutomotive air conditioning refrigerantit will come out through the small openings. You may also notice refrigerant leaks when the compressor clutch starts to fail. However, it is not impossible that the opposite is the case. In most cases, the air conditioning compressor clutch breaks in such a way that it becomes impossible to get cold air to flow. If not repaired, it can cause V-belt damage, so you don't want to extend the fix. If the clutch doesn't disengage, the air conditioning is on when it shouldn't be. If it doesn't break, you won't be able to get cold air out of the system. If the AC compressor clutch does not engage, the clutch will stop moving. Also, this noise can indicate bearing problems. The noise can be like a squeak, which is especially noticeable when you first turn it on. This noise can start before other symptoms appear, warning in advance. When the compressor clutch fails, extraneous noises appear. In any case, you should start diagnosing the problem before the problems get worse. If a compressor clutch is not constantly engaging, it can occasionally experience cold air and other times it can fail.Īlso, there is a chance of some cooler air coming out of the vents, but not enough. AC may work for a short time and then stop workingīefore the air conditioner stops completely, it may run intermittently.

That said, there are many reasons why there is a lack of cold air. If you can't feel cold air coming out of the vents, you might think a lack of coolant, only to find out that the compressor clutch is to blame. The biggest sign is that you can no longer get cold air from the air conditioner.
