A/C/Cooling Fan Controller & Wide Open Throttle A/C (WAC) Cut-Off

The A/C/Cooling Fan Controller is operated by ECA, coolant temperature switch and brake/stop light switch. Controller provides an output signal which controls operation of A/C compressor clutch and engine cooling fan.

The WAC circuit is energized by ECA when wide open throttle condition is detected. During wide open throttle, power to the A/C compressor clutch is interrupted. The A/C remains off for about 3 seconds after returning to part throttle.
