Removing

- Disconnect and isolate the battery negative cable. Refer to => [ Battery, Disconnecting and Connecting ] Tools and Equipment.

- Remove the inside rear view mirror from the mounting button on the inside of the windshield glass.

- To remove the trim cover - 4 - from over the Light Rain Sensor Module (LRSM) mounting bracket - 2 - on the inside of the windshield near the inside rear view mirror, place a thumb over the top of the cover on each side of the wiring clearance notch and hook both index fingers on the lower end of the cover. Push firmly and evenly downward with your thumbs while simultaneously pulling the bottom of the cover away from the glass with your fingers.






- Disconnect the wire harness connector - 1 - from the LRSM - 3 -.

- Depress one side of the spring steel retaining strap on the LRSM towards the windshield while lightly prying the end of the strap closest to the glass away from the tab of the mounting bracket on the windshield. Now rotate the loose side of the LRSM away from the glass far enough to disengage the other side of the strap from the mounting bracket tabs.

- Remove the LRSM from the mounting bracket.

Installing

- Depress both sides of the spring steel retaining strap on the LRSM simultaneously until the hooks of the strap engage the tabs of the mounting bracket on the windshield.

- Reconnect the wire harness connector - 1 - to the LRSM.

- Align and snap the trim cover - 4 - over the LRSM mounting bracket.

- Reinstall the inside rear view mirror onto the mounting button on the inside of the windshield glass.
