A/C Compressor Clutch Relay

The A/C compressor clutch relay supplies voltage to the A/C compressor clutch and is located in the battery junction box (BJB). The powertrain control module (PCM) can interrupt the A/C compressor operation through the A/C compressor clutch relay under the following conditions:

• During engine start-up
• Wide open throttle (WOT)
• Low engine idle conditions
• Excessively high engine temperatures
