What happens to the clutch on an AC car?
Examine the A/C clutch with a flashlight. In almost every instance when the clutch fails, it becomes burnt and discolored. The flexible, rubber isolators that allow the clutch disc to move in and out will melt from the intense heat, and the metal plates will appear rusty.
How can I tell if my a / C clutch is working?
You’ll hear a distinctive click when the compressor is energized as the drive plate is pulled into place. The electromagnet does not rotate like the clutch does. It is bolted into place on the front of the compressor. Examine the A/C clutch with a flashlight. In almost every instance when the clutch fails, it becomes burnt and discolored.
How do you test an AC clutch coil?
Touch the other wire to the positive side. If the magnet is good, the compressor clutch will click into place when the magnet powers up. Release the clutch by removing the positive wire. Repeat this procedure several times, each time listening for the clutch to energize. If the magnet is defective, replace the compressor.
Where is the clutch on an AC compressor?
It is bolted into place on the front of the compressor. Examine the A/C clutch with a flashlight. In almost every instance when the clutch fails, it becomes burnt and discolored. The flexible, rubber isolators that allow the clutch disc to move in and out will melt from the intense heat, and the metal plates will appear rusty.
What does the a / C clutch coil test do?
An A/C clutch coil is an electromagnetic device used to pull the clutch hub that’s splined to the compressor shaft into firm contact with a belt driven pulley. This action engages the compressor. Take great care when running these tests, because the coil and harness plug are very small and may be difficult to work with.

Why does clutch not engage with AC switch?
Put compressor /clutch assembly back in car and clutch would not engage with the ac switch. Checked OHMs on the coil and it was close to .4 OHMs. Bad Coils. Applied 12 volts straight to the clutch coil and still nothing happened other than wires getting hot because of a short.
When to move on to the clutch relay?
Move on to the clutch relay if the fuse turns out fine. 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. You have to make sure that the compressor has enough oil to function properly.
