When the coolant level in the system goes down, the low-pressure switch does not allow the compressor to rotate. What is the most common reason for an air conditioning compressor not to engage? Low level of refrigerant. There are a couple of ways you can fix the problem to bring back the air conditioning system in order. How To Manually Engage AC Compressor ClutchĮngaging the AC compressor clutch at home is not rocket science.

The next section tells you how to manually engage AC compressor clutch at home. When you are sure that there is a problem with the clutch, the next part is to engage it. You have to make sure that the compressor has enough oil to function properly. In a few car models, the power of the air conditioning system flows from the AC switch to the fuse before being transmitted to the clutch oil through the low-pressure evaporator temperature. Move on to the clutch relay if the fuse turns out fine. Go on to check the fuse if you cannot read the voltage readings. Use a digital voltmeter to measure the ground and voltage of the battery at the detached connector cable. Keep it safely away from all other components. In this step, you have to detach the connector cable from clutch oil. A careful inspection of the system and its components will help you to pinpoint the source of trouble. The system’s computer keeps the relay grounded but it can go on and off due to the bad switch. Working Method 2īefore starting the next step of diagnosis, you should know that a low-pressure switch can create problems with the compressor clutch’s relay in some car models. Put the AC on MAX before checking the compressor. If only the pulley is rotating, the compressor clutch is having an issue, which could be stemming from several sources – a blown fuse, bad clutch oil, low-pressure lockout, or an open wire in the oil. Also, find out whether the clutch and the pulley are spinning. Check the front side of the clutch to examine its condition. Set all air conditioning controls to the MAX before kicking off the engine. If you want to diagnose an AC compressor clutch for defects, apply these techniques: Working Method 1 In a few cases, the clutch does not engage due to a clogged refrigerant circuit. Using low-quality oil could be a reason for failing AC compressor clutch but it could happen even if you use synthetic oil and high-quality coolant. Plus, you should also know how to examine the clutch to find out if it is faulty or not. Knowing how to manually engage AC compressor clutch will help you skip a visit to the mechanic. When this component does not work properly, the engine does not get the cold air flow – leading to some major complications. An automobile can have numerous serious problems and a dysfunctional AC compressor clutch is one of them.
