1994 Geo Metro - A/C Clutch Relay
The air conditioning (A/C) clutch relay, or compressor relay, is an electrical component that connects electrical power from the vehicle's battery to the A/C compressor clutch. This controls the engagement and disengagement of the A/C compressor clutch, which is responsible for connecting the A/C compressor to power from the engine belt and pressurizing the A/C system.
