Description

The auto defog sensor is installed on the windshield. The sensor detects moisture and sends a signal when it appears, so that air is blown to remove fogging. The air conditioning control unit receives the signal from the sensor and controls the intake door, air conditioning compressor, auto defog actuator, blower fan speed and mode door to remove moisture and fogging.
