Outside Moisture Sensor Replacement Rain Sensor

1. Mark the outside moisture sensor module location on the outside of the windshield using one horizontal piece of tape (1) and one vertical piece of tape (1).
2. Disconnect the electrical connector (1) from the outside moisture sensor module (2).

Notice: Do not apply direct heat to the area around the outside moisture sensor module. Continuous exposure to heat can damage the sensor module or the windshield.

Important: Do not hold the heat gun closer than 18 cm (6 in) from the windshield. Move the heat gun around the outside moisture sensor module area. If the windshield is 61° C (110° F) or above, you may not require the heat gun.

3. Using a heat gun with a maximum of 740 watts, apply heat to the sensor area of the windshield.

Apply heat until the outside moisture sensor module may be twisted back and forth.




4. Twist the outside moisture sensor module back and forth in order to dislodge the sensor module (2).
5. Remove the outside moisture sensor module (2) from the windshield.
6. Cover the instrument panel below the outside moisture sensor module using a protective cloth.
7. Remove all optical tape from the windshield using a sharp plastic scraper.
8. Use the cloth and cleaning solution included in the service kit to wipe the windshield. Wipe the windshield until the remaining tape residue is completely removed.

Important: Ensure that the temperature of the windshield is between 30.5°C (55°F) and 55.5°C (100°F) for proper adhesion of the outside moisture sensor module.

1. Attach the outside moisture sensor module to the windshield using the following steps:

Important: Properly position the outside moisture sensor module prior to attaching the outside moisture module to the windshield. The outside moisture module cannot be moved once the outside moisture module is in contact with the windshield.

1.1.	Remove the red backing from the optical tape and immediately install the outside moisture sensor module to the windshield.

1.2.	Push the outside moisture module firmly against the windshield and hold the outside moisture sensor module in place for 10-15 seconds.

1.3.	Inspect for air bubbles between the tape and the windshield.

1.4.	Repeat the previous step under the following conditions:

•	The outside moisture sensor did not adhere to the windshield.

•	There are bubbles between the tape and the windshield.

2. Attach the electrical connector (1) to the outside moisture sensor module (2).

Do not move or shift the outside moisture sensor module on the windshield.

3. Remove the tape from the windshield.
4. Verify the operation of the outside moisture sensing wiper system.

1. Disconnect the electrical connector (1) from the outside moisture sensor module (2).

6. Remove the optical tape residue (1) from the outside moisture sensor module (3).
7. Place an aluminum plate (2) on the tape residue in order to ensure that the plate covers the entire outside moisture sensor module (3).

Notice: Do not apply direct heat to the area around the outside moisture sensor module. Continuous exposure to heat can damage the sensor module or the windshield.

8. Using a heat gun with a maximum of 740 watts, apply heat directly to the plate for approximately 60 seconds in order to soften the tape residue. Use pliers in order to remove the HOT aluminum plate from the outside moisture module.
9. Use your fingers or thumb in order to roll the tape residue down the length of the outside moisture module optical area.

Repeat this step as many times as necessary in order to remove the majority of tape residue from the optical area.




10. Fill the tray (3) to the bottom of the cut-out notch with cleaning solution.

The tray and cleaning solution are included in the service kit.

Notice: Do not allow cleaning solution to enter the outside moisture sensor module. Cleaning solution will damage the sensor module. If this occurs, the sensor module must be replaced.

11. Place the outside moisture module (1) in the tray (3) and allow the tape residue to soak for 15 minutes.

Perform step 1 of the installation procedure while the sensor is soaking.

12. Use the lint-free cloth and the cleaning solution, included in the service kit, in order to wipe the remaining tape residue off of the optical area.

Repeat step 11 if necessary. The soaking time will decrease as the amount of tape residue decreases.

13. Clean the tray (3) of all the tape residue and solution.

You will use the tray later in this procedure.

1. Use a water soluble marker or tape in order to mark the location of the outside moisture sensor module on the outside of the windshield. Complete the following steps:

1.1.	Starting at the top of the windshield, draw a line (4) perpendicular to the top of the windshield 6 cm (2.38 in) to the right of the passenger-side edge of the rear view mirror mount.
