Description The auto defogging sensor is installed on the front window glass. The sensor judges and sends signal if moisture occurs to blow out wind for defogging. The air conditioner control module receives signal from the sensor and restrains moisture and eliminate defog by controlling the intake actuator, A/C, auto defogging actuator,
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the auto defogging connector. 3. Verify that the auto defogging actuator operates to the open position when connecting 12V to terminal 3 and grounding terminal 4. Verify that the auto defogging actuator operates to the close position when connected in reverse.
