Why does AC clutch stay engaged?
The low-pressure switch tells the car that the clutch needs to engage and disengage and will shut off the A/C compressor. When the switch goes bad, it will no longer be able to measure pressure and will leave the clutch engaged the entire time.
What causes an AC compressor to get hot?
An issue called “high superheat” can be caused by not enough refrigerant in the system, a kink or restriction in the refrigerant line, a malfunctioning metering component or a hot-liquid line too close to the compressor, such as a hot-water pipe. If the compressor is short-cycling, this also can cause overheating.
Why is my AC clutch not kicking on?
One of the reasons why compressors do not engage is because of a low pressure lockout, a poor ground, a bad clutch coil, an opening in the wire to the clutch coil, or simply a blown fuse. There are several ways A/C compressor clutches receive power. With engine running, you will want to set the A/C to MAX.
