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.

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.

Notice:  DO NOT close the lift window panel with the struts attached unless the window is installed and the window adhesive fully cured. The window adds strength and rigidity to the lift window panel. Attempting to close the lift window panel, with the struts installed, without a window or with the window adhesive not fully cured, could cause the panel to crack.

1. Remove the rear lift window panel. Refer to Rear Compartment Lift Window Panel Replacement in Body Rear End.
2. Place the panel upside down on a clean protective surface.



3. Remove the auxiliary Seals.



4. Using a cold knife, cut the primary inner urethane bead from the inside of the rear lift window panel window.
5. Using J 39032 or piano wire, cut the secondary upper outer urethane bead.



6. Remove the window.
7. Clean away any loose material from the window opening.
8. Remove any old urethane from a reusable rear lift window.
9. Vacuum the vehicle to remove any trace of shattered glass.

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.

Notice:  DO NOT close the lift window panel with the struts attached unless the window is installed and the window adhesive fully cured. The window adds strength and rigidity to the lift window panel. Attempting to close the lift window panel, with the struts installed, without a window or with the window adhesive not fully cured, could cause the panel to crack.

Notice: Until the new urethane has cured, air pressure from a closing door may cause the stationary window to move causing a leak. To prevent this, lower a window before closing the door.

1. Install the rear lift window panel, but do not install the struts. Refer to Rear Compartment Lift Window Panel Replacement in Body Rear End.
2. Latch the panel.
3. Clean the replacement window surface to which the urethane is to be applied with an alcohol dampened cloth. Allow the alcohol coated surface to air dry.
4. Apply Clear Glass Prep #1 with a clean dauber to the surface of the window that will contact the urethane area of the panel. Wipe the window dry with a clean lint free rag.

Important: 

•	Urethane will not bond to the window unless Black Primer #2 has been applied to the window.

•	Do Not apply Black Primer to the existing urethane on the lift window panel.

5. Apply Black Glass Primer #2 with a clean dauber to the surface of the window that will contact the urethane and allow the primer to air dry for 6 to 10 minutes.



6. Position the window to the panel.
7. Gap the window:

•	Use 7 mm x 30 mm (0.23 in x 1.2 in) spacers.

•	Insert the spacers 0.3 meters (1 ft) from the center on each side of the upper edge of the roof bow.

8. Align the window to the opening.
9. Mark the window position on the window and on the panel.
