Compressor Clutch Relay: Description and Operation

The A/C clutch control relay is used by the PCM to turn "ON" or "OFF" the A/C compressor clutch coil. When the PCM receives an A/C request signal,
it will supply a ground to the A/C clutch control relay, energizing the relay and allowing the A/C compressor clutch coil to be energized. This allows the
A/C compressor to be turned "ON". During certain driving conditions, the PCM will turn "OFF" the A/C compressor by removing the ground for the
A/C clutch control relay.
