Removal

2. Press the spring clip while lifting the corners of the clip to remove the sensor from the bracket.

   

Installation procedure is the reverse of removal, except for the following:

Note: The light/rain sensor is a one time use component. If the rain/light sensor is removed from the windshield, a new sensor must be installed.

1. Inspect the mounting bracket for excess adhesive. If necessary, use a knife or razor blade to remove any excess adhesive around the inner edge of the bracket.

   

2. Clean the glass surface before installing the light/rain sensor.
3. To test the rain sensor operation, sit in the driver's seat. Set the wipers to the 1st or 2nd intermittent position while an assistant sprays the windshield with water. Check that the wipers sweep when water is sprayed in front of the sensor.
4. To test the light sensor operation, have an assistant shine a bright light on the sensor for several seconds. Check that the touchscreen changes from night to day brightness.
