Tools Required

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

1. Remove the rear quarter trim finish panels. Refer to Rear Quarter Upper Trim Panel Replacement in Interior Trim.



2. Disconnect the rear window defogger electrical connectors from the right and left sides of the rear window.

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.

3. Use safety glasses and gloves.
4. Open the rear compartment lid in order to access the reveal molding (1).




Important: The rear window reveal molding fills the cavity between the body and window and cannot be reused if stretched or damaged.

5. Remove the rear window reveal molding.

4.1.	Grasp the lower corner of the rear window reveal molding (2) with your hand and slowly pull the reveal molding away from the rear window.

4.2.	If the rear window reveal molding will not release use a utility knife to cut around the windshield to remove the rear window reveal molding.




6. Using a sharp utility knife, make a preliminary cut around the perimeter of the rear window, cut as close to edge of the rear window as possible.




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.

7. Use the J 24402-A or J 39032 in order to cut the rear window from the pinchweld flange.

Keep the cutting edge of the tool against the window when cutting around the stationary window to achieve the best cut.




8. With the aid of an assistant, use the suction cups in order to lift the rear 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 conditions in order to prevent damage to the rear window:

•	A high weld

•	Solder spots

•	Hardened spot weld sealer

•	Any 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 windshield opening and the adhesive bead to determine which installation method should be used. Refer to Short Method Description or Extended Method Description for guidelines.

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 windshield and the pinchweld flange.

4.3.	Remove all traces of broken glass from the outer cowl panel, seats, floor and defroster ducts.

4.4.	Clean around the edge of the inside surface of the windshield 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 one 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 primer (black #3) to the pinchweld surface (1) of the bonding area on the body only.
7. Allow the primer to dry for approximately 10 minutes. Ensure that all nicks and scratches are covered.



8. Install the new rear window reveal molding. Refer to Rear Window Reveal Molding Replacement .
