Tools Required

1. Unclip the defogger connector at the left and right side of the window from the inside of the cab, if equipped.
2. Remove all trim panels necessary in order to gain access for rear window removal.



3. Use the J 39032 from the inside of the window and J 24402-A from outside to remove the glass assembly from the window frame.
4. With an assistant standing outside of the vehicle, push the window out from the vehicle.

1. Apply body primer to the pinchweld flange (3) in areas where the paint has come off.

Use repair kit GM P/N 12346284 or equivalent that contains the proper primers and adhesive.

2. Allow the primer to dry.



3. Apply clear primer to the window, covering an area of 18 mm (3/4 in) from the edge of the glass.
4. Apply black primer to the same area as the clear primer in the step above.
5. Allow the primer to dry.
6. Apply a urethane adhesive bead to the body in order to fill in any gaps in the old adhesive.
7. Connect the defogger clips on each side of the window on the inside to the body connectors, if equipped.
8. Install all trim panels which were removed in order to gain access for rear window removal.
9. Ensure that the two tabs on the bottom of the window are positioned in the slots on the body before installing the sliding window.

Important: 

•	Allow the vehicle to remain at room temperature 22°C (72°F) at 30% relative humidity) for a minimum of 6 hours.

•	Partially lower a door window in order to prevent pressure build ups when closing the doors prior to the urethane adhesive cure.

•	Do NOT drive the vehicle until the urethane adhesive is cured, a minimum of 6 hours at room temperature.

•	Do NOT use compressed air to dry the urethane adhesive.

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

10. Watertest the window immediately using a soft spray. Use warm or hot water spray in order to accelerate the cure of the adhesive.
