Description

The auto defogger sensor is installed on the windshield glass. The sensor detects moisture and sends a signal when the defogging wind is blown to prevent fogging. The A/C control module receives the signal from the sensor and controls the intake actuator, the A/C compressor, the auto defogger actuator, the blower motor speed, and the mode actuator to remove moisture and eliminate fogging.
