What causes an AC compressor clutch to not engage?

What’s Preventing the A/C Compressor from Engaging? 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.

Is the AC clutch supposed to spin all the time?

The compressor’s idler pulley is always rotating since the serpentine belt is turning to power water pump, power steering pump, and alternator. With ac off (engine running) the drive belt still turns the compressor idler pulley. With ac on, the large center clutch should turn with the belt.

How do I know if my AC clutch is seized?

Both the outer pulley and the inner hub should be turning, indicating the clutch is engaged and driving the compressor. If the compressor is seized, the entire clutch assembly will be stationary and the belt will be slipping, squealing, smoking and, in a very short period of time, failing.

What causes AC clutch to lock up?

If the clutch pulley locks up, it means either the spin ing idle pulley against which the clutch engages is jammed due to a faulty bearing or the clutch itself due to the compressor jammed. The fix could be either a change of pulley bearing or the compressor service. The clutch bearing goes bad and seizes up.

Will AC compressor spin without belt?

But if your car, truck, or SUV has a separate drive belt for the AC compressor, the only system affected would be the AC.

What controls the AC clutch?

Switches, relays and transducers control the clutch (and therefore the compressor), keeping the system operating smoothly – and, in the event of failure, shutting the compressor down to prevent catastrophic failure.

Should the AC compressor clutch always engaged?

Unplug the electrical connector on the compressor and see if it disengages then. If it doesn’t, there’s something wrong with the clutch. If it does, it’s working fine.
