How do you turn off an air conditioner relay?
Turn off the air conditioning unit’s circuit breaker or disconnect switch. Most units have a disconnect box within 3 feet of the unit’s control panel that contains a circuit breaker-type switch, or a pull-out buss bar. If not, turn off the system at the circuit breaker panel. Compare the new relay to the old one.
Where is the relay on an air conditioner compressor?
If these conditions are met, the module will energize the A/C relay coil when the A/C button is pushed. This allows power to flow through the relay to the compressor clutch, turning your A/C on. Step 1: Locate the A/C relay. The A/C relay is typically found in the underhood fuse box. Consult your owner’s manual for the exact location.

How does the a / C relay work on a car?
The electronic control module monitors the status of sensors in your vehicle to determine if the conditions are correct for A/C operation. If these conditions are met, the module will energize the A/C relay coil when the A/C button is pushed. This allows power to flow through the relay to the compressor clutch, turning your A/C on.
