If there’s a problem with any of them, the clutch could fail to work. Your car’s AC system contains many electrical wires and connections.

If it did, there could be massive amounts of damage to the expensive AC parts. Check your owner’s manual to find the fuse for the AC clutch. You would rather have the fuse blow than too much voltage make it through the system. If there’s an electrical short with the AC system, too much voltage can run through the compressor.

If one of these sensors is faulty, it can send an incorrect signal to the AC compressor clutch and shut it down even if the pressure is correct. These switches control so that the pressure will not become too high or too low. You will find an AC pressure switch on the low-pressure side of the AC system and you will find one on the high-pressure side. RELATED: 5 Signs Your Car’s AC is Low on Freon (& What to do) 2. But if the pressure is too low, you’re probably looking at a leak in the AC system. Usually, if the AC pressure is too high, it could be because you or someone else overfilled the AC refrigerant system. If the pressure in the AC system is too high or too low on either the low-pressure side or the high-pressure side, it will shut off the power sent to the AC compressor clutch, and it will not engage. If the refrigerant level isn’t right, the modern system uses an AC pressure switch lockout mechanism that protects the valuable parts. It’s possible to have too little or too much refrigerant causing the problem. The air conditioning system needs the right amount of refrigerant to run properly. Here is a more detailed list of the most common reasons why your AC clutch is not engaging: 1.
It can also be caused by a faulty high or low AC pressure switch, a blown fuse, a bad AC clutch or a bad electrical connection. The most common reason why your AC clutch is not engaging is that the AC refrigerant level is too low or too high. Is the AC clutch supposed to spin all the time?
