Tools Required

The quarter window is made of a solid tempered safety glass encapsulated by the reveal molding. Urethane adhesive is used to secure the window module to the body opening. Service the following components as an assembly:

Secure the quarter window applique to the quarter window using the locking tabs. Use a urethane adhesive in order to secure the quarter window applique to the body opening.

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.

1. Remove the rear quarter trim panel. Rear Quarter Trim Panel Replacement in Interior Trim.

The body

Important: 

•	Refinish the pinchweld flange in order to present a PRIMER ONLY surface under the following conditions:

-	Corrosion of the pinchweld flange is present

-	Sheet metal repairs or replacements are required

•	If paint repairs are required, mask the flange bonding area, prior to applying the color coat, in order to provide a PRIMER ONLY surface.

•	Use the following 2-part, catalyzed products for primer application:

-	BASF DE 17

-	DUPONT 2610

-

PPG DP90

•	Follow the manufacturer's instructions for the following primer application steps:

-	The mixture

-	The application

-	The dry times

•	After repairing the opening as indicated, perform the following steps:

-	Thoroughly shake the pinchweld primer #3 (black).

-	Use a new dauber to apply the primer to the primed surface of the flange in the bonding area.

-	Allow the primer to dry 10 minutes.

8. Inspect the body pinchweld for any damage.

Repair all damage before continuing with the quarter window replacement.

1. Attach the quarter window applique tabs to the quarter window molding slots.
2. Dry fit the glass into the body opening in order to determine the correct position.
3. Perform the following procedures:

3.1.	Position the window in the opening.

3.2.	Use masking tape to mark the location of the glass in the opening on one horizontal edge of the glass.

Use masking tape to mark the location of the glass in the opening on one vertical edge of the glass.

3.3.	Slit the masking tape at the glass edges.

Remove the window from the body opening.

3.4.	Place the window on a clean protected work surface with the inside surface facing up.

4. If reinstalling the original window, use a razor knife to remove any existing urethane adhesive from the edge of the glass surface.
5. Clean the surface of the window to which the urethane adhesive is being applied (around the edge of the inside surface).

Use the following solutions to clean the glass surface:

•	An Isopropyl alcohol dampened cloth

•	GM Glass Cleaner P/N 1050427, or equivalent

Important: Primer application is important because primers act as an agent that will bond the urethane to the applique. Use the specified primer for each application in order to ensure the proper adhesion.

6. Thoroughly shake the pinchweld primer #3 (black). Apply the primer to any exposed surfaces where the urethane contacts the body.

Allow the primer to dry for 10 minutes.

Do not apply black pinchweld primer to any existing urethane surface.

Important: Use care in order to prevent glass prep #1 (clear) from running into the vision area of the glass. Glass prep #1 dries nearly instantly. Apply the primer evenly in order to not stain the viewing area of the window.

7. Using a new dauber, apply PVC primer #4 (clear) to the quarter window where the urethane is to be applied. Wipe the quarter window dry with a clean cloth.
8. Shake the glass primer #2 (black) well. Use a new dauber in order to apply the primer to the same areas to which you apply the glass prep #1.
9. Allow the primer to dry for approximately 6 to 10 minutes.

Important: 

•	DO NOT apply clear primer over black primer.

•	DO NOT touch the primer coated surfaces.

10. Tape the rear window reveal molding away from the applique in order to assist the installation.
