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.
