The system’s computer keeps the relay grounded but it can go on and off due to the bad switch. Or you can, before 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. 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. Lets make sure your AC is working well, and get started. It could be anything from an obstruction in the refrigerant circuit to a loose wire. We’ll talk about the possible problems and solutions for a compressor clutch that is not engaging. You may decide to check the engine coolant and the engine oil as well to rule out other issues, but the clutch if the component that must function in order for the AC to work. If the AC is not blowing cool air into the car, you may want to do a visual inspection of the AC compressor clutch and determine if you can see what might be causing the clutch to not engage.Įven if you just filled up the AC system with refrigerant, if the AC compressor can’t operate correctly, you’ll get warm air. If the compressor clutch doesn’t engage that usually means, there’s an electrical or mechanical problem with the compressor. The compressor could have a serious issue or a small one. What could be the problem? If suddenly, the AC compressor clutch stops working and doesn’t engage, this could be the reason your AC isn’t functioning properly. However, when you turn on the air conditioner it only blows warm air. Imagine, you’ve got a car and it all works so fine. ![]()
