Cause
An aftermarket recommendation is needed for replacing the windshield without the

Solution
Note: As an OEM we recommend utilizing genuine approved parts for replacement. This
procedure is an aftermarket recommendation for replacing the windshield without the
factory black “Frit” around the Rain Sensor for the North American Market.
Tools and equipment needed for reinstall or bracket transfer:
Glass Cleaner
Adhesive Removal
Adhesive
Heat Gun
Sensor Mounting Bracket ( P/N 21351909 )
Dry Erase Marker
Measuring Tape
Utility Knife & Blades
Painters Tape
Caulk Gun
Sensor Gasket ( P/N 21836770 )
Reinstallation Procedure
1. Disconnect the rain sensor from the damaged windshield. Windshield will need to be
removed to remove the rain sensor bracket.
2. Press on the metal hold down clip and use a flat blade screwdriver and pry outward on the
sides holding the sensor to the bracket.
2a. Removed sensor, position sensor and wire out of the way for damaged windshield
removal
3. Begin by using the heatgun to heat the adhesive on the current bracket.
4. As the adhesive is heating up, use a razor knife/blade to gently slice at the adhesive
until it begins to free up. *DO NOT PRY UP THE BRACKET*
5. Using a razor blade or knife carefully scrape the excess leftover adhesive. Underside
needs to be as clean as possible for reapplication.
Bracket Removed
6. With the new windshield face down measure out 17 and 1/16th of inch from the right
inside black edge of the windshield
7. With the new windshield face down measure out 3 and 3/4th of inch from the very
bottom edge of the windshield
*Utilize the dry erase marker and painters tape to mark off where the bracket will
go*
8. With the area measured off use the painters tape to mark off the area where the bracket will
go. Re-measure- *placement needs to be approximate not exact*
9. Clean the surface of the windshield using GC-800 Glass cleaner
10. Using U-418 (adhesive and caulk gun) apply the adhesive to the back side of the
bracket and press down to the glass within the taped off area. *Ensure that adhesive does
not bleed into the center area, as that will interfere with clear sensor gasket application.*
*Note the 4 raised points on the backside of the bracket. Adhesive application needs
to be liberal enough to ensure a proper contact patch to the windshield, as these 4
raise points will contact the glass first*
Recommended curing time for adhesive:
15-30 mins-workable
24 hours fully cured
*time may vary depending on temp and humidity*
11. Once the bracket has settled within the tack free/working time frame, installation of
the new windshield can be performed, however it is recommended to wait the full 24
hours for full cure.
12. Install Sensor Gasket Part# 21836770, by removing protective film from back side,
install in direct center point of bracket, remember to remove the remaining plastic
protective film and try to minimize the amount of air bubble between glass and gasket.
Recommended curing time for adhesive:
15-30 mins-workable
24 hours fully cured
*time may vary depending on temp and humidity*
13. With the gasket installed, reverse steps 1 and 2 for reconnecting the Rain Sensor.
