Tools Required

Caution: When working with any type of glass or sheet metal with exposed or rough edges, wear approved safety glasses and gloves in order to reduce the chance of personal injury.

1. Use safety glasses and gloves.

Important: Before cutting out a stationary window, apply a double layer of masking tape around the perimeter of the painted surfaces and inner trim of the window.

2. Gently disengage the plastic retainers that retain the air outlet molding.
3. Remove the air outlet molding from the vehicle.




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

4. Use the J 24402-A (1) or J 39032 in order to remove the quarter window.



5. Gently unseat the quarter window retainer-male ends (1) on the window (2) from the quarter window retainer-female ends (4) on the body.
6. Use suction cups in order to lift the quarter window (2) and quarter window reveal molding (3) as an assembly 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 quarter window:

•	The flange of the quarter window opening

•	The quarter window reveal molding

3. Inspect for any of the following problems in order to help prevent future breakage of the quarter 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 necessary, 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 quarter 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 quarter 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 quarter window with a 50/50 mixture of isopropyl alcohol and water by volume on a dampened lint free cloth.

1. 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.

2. Use a new dauber to apply the pinchweld primer (black #3) to the surface of the bonding area.
3. Allow the primer to dry for approximately 10 minutes. Ensure that all nicks and scratches are covered.



4. If the original reveal molding is damaged it must be replaced.

Install the new quarter window reveal molding (3) to the quarter window (2). Refer to Quarter Window Reveal Molding Replacement .

5. Dry fit the quarter window (2) in the opening in order to determine the correct way to position the quarter window in the opening.
6. Use masking tape in order to mark the location of the quarter window in the opening.
7. Slit the masking tape at the top edge of the quarter window.
8. With the aid of suction cups, remove the quarter window (2).



9. Place the quarter window (1) inside up on a clean, protected surface.
10. If the original window is being reused, remove all but a thin film of the existing urethane adhesive from the quarter 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.

11. 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.
12. 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.

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




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

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



17. Apply a second coat of the glass prep (clear #1) to the same area of the glass.
18. Wipe the glass primed area immediately with a clean lint free cloth.
19. Shake the glass primer (black #2) for at least 1 minute.



20. Shake the rear window primer (black #2) for at least one minute.
21. Use a new dauber, in order to apply the rear window primer (black #2) (2) to the same areas that glass prep (clear #1) was applied.

The glass primer (black #2) is good up to 8 hours after applying it to the glass. The primed surface of the glass must be kept clean.

22. Allow the primer to dry for approximately 10 minutes.



23. If using the short method, cut the tip of the applicator nozzle in order to provide a bead of 6.0 mm (1/4 in).
24. If using the extended method, cut the applicator nozzle in order to provide a bead 12.7 mm (0.5 in) wide and 12.7 mm (0.5 in) high.



25. Use a cartridge-type caulking gun to apply a smooth, continuous bead of urethane adhesive.
26. When using the short method, apply the urethane adhesive to the existing bead of urethane adhesive on the body.
27. When using the extended method, use the edge of the quarter window or the inside edge of the reveal molding as a guide for the nozzle in order to apply the urethane adhesive to the inner surface of the quarter window.



28. With the aid of suction cups, install the quarter window (2) into the opening.
29. Align the tape on the quarter window and on the body.
30. Press the quarter window (2) firmly into place.
31. Tape the quarter window to the body in order to minimize movement until the urethane adhesive cures.



32. Clean any excess urethane adhesive from the body.




Important: Do not direct a hard stream of high pressure water to the freshly applied urethane adhesive.

33. Use a soft spray of warm water in order to immediately water test the quarter window.
34. Inspect the quarter window for leaks.
35. If any leaks are found, use a plastic paddle in order to apply extra urethane at the leak point.
36. Retest quarter window for leaks.

Caution: Insufficient curing of urethane adhesive may allow unrestrained occupants to be ejected from the vehicle resulting in personal injury.

•	For the moisture-curing type of urethane adhesive, allow a minimum of 6 hours at 21°C (70°F) or greater and with at least 30 percent relative humidity. Allow at least 24 hours for the complete curing of the urethane adhesive.

•	For the chemical-curing type of urethane adhesive, allow a minimum of 1 hour .

Do NOT physically disturb the repair area until after these minimum times have elapsed.
37. The following conditions must be maintained to properly cure the urethane.

37.1.

Partially lower a rear door window in order to prevent pressure buildups when closing doors before the urethane adhesive cures.

37.2.

Do not drive the vehicle until the urethane adhesive is cured. Refer to the above curing times.

37.3.

Do not use compressed air in order to dry the urethane adhesive.

38. Install the plastic retainers to the air outlet molding. Replace with new retainers as needed.
39. Install the air outlet molding to the vehicle. Ensure that the plastic retainers are completely engaged.
