Customer Question

I have a 1998 Monte Carlo. I was driving down the highway when I heard a loud noise. I looked up in my rearview mirror, and my rear window had shattered. It was only about 69 degrees outside, there was condensation on my rear window when I left so I turned the rear window defrost on which will only stay on for about 5-8 minutes and automatically shut down. I had the a/c on the lowest setting and I was about 15 minutes into my drive when it happened. I was able to turn around and go home with most of the window intact. and now that I am home I removed all but a small portion around the perimeter. I found a salvage yard that has one for about $50 and I know I would have to buy a new gasket. Is this a job a do it yourselfer might be able to do , or should I take it to a glass shop where it will cost me over $200. My deductible is too high to even consider using insurance to pay for it. and replacement instructions would be needed for me to replace myself. I would also have a couple of helpers.

Rear Window Replacement

Tools Required
* J 24402-A Glass Sealant Remover (Cold Knife)
* J 39032 Stationary Glass Removal Tool
* J 34940 Rivet Gun
* Urethane Adhesive Kit GM P/N 12346392 or Equivalent
* Isopropyl Alcohol or Equivalent
* Cartridge-type Caulking Gun
* Commercial-type Utility Knife
* Razor Blade Scraper
* Suction Cups
* Plastic Paddle

Removal Procedure

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.


1. Remove the rear window reveal molding. Refer to Rear Window Reveal Molding Replacement ( See: Back Window Glass Moulding / Trim > Removal and Replacement > Rear Window Reveal Molding Replacement).

3. Disconnect the rear window radio antenna connector.

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.

Important: Keep the cutting edge of the tool against 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.


4. Use J 24402-A or J 39032 in order to cut the stationary window from the pinchweld flange. Do this from inside the vehicle in order to protect the outer paint surface.








58_gc01vbdyA-412291.png

5. With the aid of an assistant, use the suction cups in order to lift the rear window from the opening.

Installation Procedure

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 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(R), DuPont 2610(R), Sherwin-Williams PSE 4600 and NP 70 and Martin-Semour 5120 and 5130 products are approved for this application.


4. After repairing the opening as indicated, perform the following steps:
Inspect the condition of the rear window opening and the urethane adhesive bead in order to determine which installation method you will use. Refer to Short Method Description ( See: Windows > Components > Short Method Description) or Extended Method Description ( See: Windows > Components > Extended Method Description) for the guidelines.
5. Remove all traces of broken glass from the vehicle.
6. 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.
7. After repairing the opening as indicated, shake the pinchweld primer (black #3) for at least one minute.








03_gc01mlbdyA-245283.png
Full Size Image



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.

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

10. If the original reveal molding is damaged it must be replaced.
Install the new rear window reveal molding (1). Refer to Rear Window Reveal Molding Replacement ( See: Back Window Glass Moulding / Trim > Removal and Replacement > Rear Window Reveal Molding Replacement).
11. Start from the center and hand press the rear window reveal molding (1) onto the rear window (2).
12. With the aid of an assistant, dry fit the rear window in the opening in order to determine the correct way to position the rear window in the opening.
13. Use masking tape in order to mark the location of the rear window in the opening.
14. Slit the masking tape at the top edge of the rear window.








58_gc01vbdyA-412291.png

15. With the aid of an assistant and the suction cups, remove the rear window.
16. Place the rear window inside up on a clean, protected surface.
17. If the original windshield is being reused remove all but a thin film of the existing urethane adhesive from the windshield surface 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.


18. 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.
19. 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.

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.


20. Shake the pinchweld primer (black #3) for at least one minute.
21. Use a new dauber to apply the primer to the surface of the pinchweld flange.
22. Allow the pinchweld primer to dry for approximately 10 minutes.
23. If the extended method is being performed, do the following:








47_gc01vbdyA-154028.png
Full Size Image



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


24. If installing a new non encapsulated window:

1. Use a new dauber, to apply the rear window prep (clear #1) to an area approximately 10 to 16 mm (3/8 to 5/8 in) around the entire perimeter of the rear glass inner surface.
2. Apply the rear window prep (clear #1) to the same area of the glass.
3. Wipe the primed window area immediately with a lint-free cloth.
4. Shake the glass primer (black #2) for at least one minute.
5. Use a new dauber, to apply the rear window prep (clear #1) to an area approximately 10 to 16 mm (3/8 to 5/8 in) around the entire perimeter of the rear glass inner surface. The glass must be installed within 8 hours after applying the primer to the glass.
6. The primed surface of the glass must be kept clean.
7. Allow the glass primer to dry for approximately 10 minutes.

25. Shake the rear window primer (black #2) for at least one minute.

26. Use a new dauber, in order to apply the rear window primer (black #2) to the areas of the rear window (1) to which prep (clear #1) was applied.
27. Allow the primer to dry for approximately 10 minutes.

34. Align the tape on the rear window and on the body.
35. Press the rear window firmly into place in order to wet-out and seat the urethane adhesive.
36. Tape the rear window in places to the body in order to minimize movement until the urethane adhesive cures.

Important: Do not direct a hard stream of high pressure water at the fresh urethane adhesive.


38. Use a soft spray of warm water in order to immediately water test the rear window.
39. Inspect the rear window for leaks.
40. If any leaks are found, use a plastic paddle in order to apply extra urethane at the leak point.
41. Retest the rear 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.

42. The following conditions must be maintained to properly cure the urethane.

1. Partially lower a door rear window in order to prevent pressure buildups when closing doors before the urethane adhesive cures.
2. Do not drive the vehicle until the urethane adhesive is cured. Refer to the above curing times.

Thank you, XXXXX XXXXX a quote from glass repair down the road for 210, right now I'm leaning in that direction, after I buy primer, adhesive, gasket and window, I probably wouldn't be much better off and less aggravation not to mention it might end up a botched job so I think I'll play it safe this time.
