What is an Ac Clutch Relay?

An Ac clutch relay is an electrical device that is used to activate or deactivate the AC compressor. When the system detects a problem with the AC compressor, it will send a signal to the clutch relay. The relay will then activate the AC compressor, which will help to fix the problem.

How to Test an Ac Clutch Relay

An ac clutch relay is a device that controls the operation of the AC compressor. When the clutch relay fails, the AC compressor will not operate. To test an ac clutch relay, first ground the power to the AC compressor. Then test each input with a known good relay. If one input is good, then there is a problem with the ac clutch relay and it should be replaced.

What to do if the Ac Clutch Relay is Not Working Properly

If you’re experiencing problems with your Ac clutch relay, there are a few things you can do to diagnose and fix the issue. The most common symptom of a failed Ac clutch relay is a loss of power to your AC compressor. To test the Ac clutch relay, first try turning off your car’s ignition and then cycling the AC power button on the instrument panel. If the relay is faulty, you’ll see no response from the button. If your car has R-134a air conditioning, you may also experience a loss of cooling due to a faulty Ac clutch relay. In this case, you’ll need to replace the relay.


If you are experiencing issues with your Ac clutch relay, it is important to troubleshoot the issue before going any further. Test the relays by disconnecting each one and testing them individually; if one relay goes bad, it is likely that both have gone bad. If you are still having issues after trying these troubleshooting steps, it may be necessary to replace the relay.
