Important: The rear door window reveal molding fills the cavities between the body and rear door window and can not be reused if stretched or damaged.

8. Remove the rear door window reveal molding.
9. Grasp the lower corner of the rear door window reveal molding by hand and slowly pull the reveal molding away from the rear door window.
10. If the rear door window reveal molding will not release, use a utility knife in order to cut around the rear door window in order to remove the reveal molding.




Important: Keep the cutting edge of the tool against the rear window when removing the rear window. This will allow the urethane adhesive to be separated from the rear window. Leave a base of urethane on the pinchweld flange. The only suitable lubrication is clear water.

11. Use the J 24402-A orJ 39032 in order to remove the rear door window.
12. Gently unseat the rear door window retainer-male ends on the window from the rear door window retainer-female ends on the door.
13. With the aid of an assistant, use the suction cups in order to lift the rear door window from the opening.

1. Verify all primers and urethane adhesive are within expiration dates.

Caution: When replacing stationary windows, use Urethane Adhesive Kit GM P/N 12346392 (Canadian P/N 10952983), or a urethane adhesive system meeting GM Specification GM3651G, to maintain original installation integrity. Failure to use the urethane adhesive kit will result in poor retention of the window which may allow unrestrained occupants to be ejected from the vehicle resulting in personal injury.

2. Inspect the following components for the causes of a broken rear window:

•	The flange of the rear window opening

•	The rear window reveal molding

3. Inspect for any of the following problems in order to help prevent future breakage of the rear window:

•

High weld

•	Solder spots

•	Hardened spot weld sealer

•	Any other obstruction or irregularity in the pinchweld flange

Important: If corrosion of the pinchweld flange is present, or if sheet metal repairs or replacements are required, the refinish the pinchweld flange in order to present a clean primer only surface. If paint repairs are required, mask the flange bonding area prior to the application of the color coat in order to provide a clean primer only surface. Materials such as BASF DE17®, DuPont 2610®, Sherwin-Williams PSE 4600 and NP70® and Martin-Semour 5120 and 5130® products are approved for this application.

4. After repairing the opening as indicated, perform the following steps:

4.1.	Inspect the condition of the rear window opening and the urethane adhesive bead in order to determine which installation method should be used.

4.2.	Remove no more of the urethane adhesive from the pinchweld than necessary in order to maintain the original shape. This will ensure the proper clearance between the rear door window and the pinchweld flange.

4.3.	Remove all traces of broken glass from the vehicle.

4.4.	Clean around the edge of the inside surface of the rear window with a 50/50 mixture of isopropyl alcohol and water by volume on a dampened lint free cloth.




5. After repairing the opening as indicated, shake the pinchweld primer (black #3) for at least 1 minute.

Caution: Failure to prep the area prior to the application of primer may cause insufficient bonding of urethane adhesive. Insufficient bonding of urethane adhesive may allow unrestrained occupants to be ejected from the vehicle resulting in personal injury.

6. Use a new dauber to apply the pinchweld primed (black #3) to the surface of the bonding area.
7. Allow the primer to dry for approximately 10 minutes. Ensure that all nicks and scratches are covered.
8. Install a new rear door window reveal molding. If the original reveal molding is damaged it must be replaced. Refer to Rear Window Reveal Molding Replacement .
9. With the aid of an assistant, dry fit the rear door window in the opening in order to determine the correct way to position the window in the opening.
10. Use masking tape in order to mark the location of the rear door window in the opening.
11. Slit the masking tape at the top edge of the rear door window.
12. With the aid of an assistant and the suction cups, remove the rear door window.



13. Place the rear door window (1) inside up on a clean, protected surface.
14. If the original window is being reused, remove all but a thin film of the existing urethane adhesive (2) from the window surface by using a clean utility knife or razor blade scraper.

Important: Do not remove all traces of the adhesive. Remove all mounds or loose pieces of urethane adhesive .

15. If the extended method is being used remove all but approximately 2 mm (3/64 in) of the existing bead of adhesive from the pinchweld flange.
16. Clean around the edge of the inside surface of the window with a 50/50 mixture of isopropyl alcohol and water by volume on a dampened lint free cloth.

Important: Do not apply the (black #3) primer to the existing bead of the urethane adhesive. Apply the primer only to nicks, scratches or the primed surfaces.

17. Shake the pinchweld primer (black #3) for at least 1 minute.
18. Use a new dauber to apply the primer to the surface of the pinchweld flange.
19. Allow the pinchweld primer to dry for approximately 10 minutes.




Important: Use care when applying the prep (clear #1) to rear door window. This primer dries almost instantly, and may stain the viewing area of the rear window if not applied evenly.

20. Use a new dauber in order to apply the glass prep (clear #1) to the area approximately 10-16 mm (3/8-5/8 in) around the entire perimeter of the window inner surface.



21. Apply a second coat of glass prep (clear #1) to the same area of the glass.
