Liftgate Window Glass: Service and Repair

Liftgate Window Replacement

Removal Procedure





Caution: Refer to Glass and Sheet Metal Handling Caution in Cautions and Notices.

Notice: Care must be taken to avoid damaging paint around glass during removal.

1. Remove the lift gate trim panel.
2. Unsnap the center high-mount stop lamp cover.




3. Unsnap the center high-mount stop lamp housing and disconnect the wire connector.




4. Remove the electrical connectors from the rear window defogger bus bars. Mark both the inside and outside of the glass with tape to identify the electrical connector locations. Position the electrical connectors so not to damage the wiring/connectors when using the urethane power removal tool.




5. Remove the wiper arm, finish cap, nut, and washer.
6. Remove the spacer, shaft nut, washer, and bezel.
7. Apply two 15 cm (6 in) pieces of duct tape to the top and bottom of the glass to prevent it from falling out when the urethane adhesive is cut.




Caution: Refer to Urethane Smoke Caution in Cautions and Notices.
8. From the inside of the lift gate, cut the urethane around the glass using a power glass removal tool.
9. Remove the window assembly.



Installation Procedure


Important: Loose urethane and/or a rough surface on the remaining urethane may cause sealing problems during installation.


1. Remove the old urethane with a razor knife leaving a thin film, approximately 1-2 mm (0.04-0.08 in) around the perimeter of the window opening and window assembly, if being reused.
2. Clean the surface of the glass where the adhesive is to be applied with a clean, alcohol-dampened cloth. Allow to air dry.





Important: Shake the glass prep primer (Clear #1) well before using.


3. For new lift gate glass only, apply the glass prep primer (Clear #1) around the entire perimeter of the glass using a dauber. Wipe dry with a clean, lint-free cloth.

The primer area minimum width (A) is 18 mm (0.71 in).


Important: Shake the glass primer (Black #2) well before using.


4. With a new dauber, apply the glass primer (Black #2) around the entire perimeter over Clear #1. Allow the primer to dry 5 minutes.

The primer are minimum width (A) is 18 mm (0.71 in).

5. Apply a smooth continuous bead of urethane adhesive around the perimeter of the lift gate glass. Apply the urethane up to the edge of the encapsulated molding.

* The bead dimension for the minimum width (B) is 8 mm (0.32 in).
* The bead dimension for the minimum height (C) is 14 mm (0.55 in).






6. With the aid of an assistant, align the window assembly onto the wiper module shaft. Press the glass firmly around the perimeter of the wiper module shaft and glass to wet-out and set the adhesive. Use care to avoid excessive squeeze out which would cause an appearance problem. Use tape from the glass to the lift gate to hold in position until the urethane adhesive is cured.

Notice: Until the new urethane has cured, air pressure from a closing door may cause the glass to move. To prevent this, lower the opposite side door window a minimum of 76 mm (3 in) before closing the door.

7. Watertest the vehicle using a soft spray. Use warm or hot water if available. Do not direct a hard stream of water at the fresh adhesive material. Water applied on top of the urethane adhesive, either during watertest or part of a separate operation, will speed up the cure of the urethane.
8. Inspect for leaks from inside the vehicle. Paddle in extra adhesive at the leak points using a tongue depressor or similar flat flexible tool.




9. Install the bezel, washer, shaft nut, and spacer.
10. Install the wiper arm.

Notice: Refer to Fastener Notice in Cautions and Notices.

11. Install the washer and nut.

Tighten the rear wiper arm nut to 8 N.m (72 lb in).

12. Install the wiper arm finish cap.




13. Connect the rear window defogger electrical connectors to the bus bars.




14. Install the center high-mount stop lamp.




15. Install the center high-mount stop lamp cover.

Important: The vehicle must remain at normal room temperature for 6 hours to complete the proper cure of the adhesive. Refer to the manufacturer's recommendation.


16. Install the lift gate trim panel.
