Window Glass - Rear Quarter
NOTE: LH shown, RH similar.
Removal
1. Remove the rear quarter trim panel.
2. Remove the wiring harness brackets.
3. Before cutting the urethane adhesive, remove dirt and other foreign material from the windshield pinch weld area.
- Use a clean shop towel or oil-free compressed air.
4. WARNING: Always wear eye protection when servicing a vehicle. Failure to follow this instruction may result in serious personal injury.
WARNING: Wear protective gloves when handling components or parts that have pointed or sharp edges. Failure to follow this instruction may result in serious personal injury.
NOTICE: To avoid rust formation, use extreme care not to scratch the paint or primer or otherwise damage the pinch weld during glass removal.
NOTE: Insert the blade into the Deluxe Windshield Removal Tool so that the flat side is against the glass. This will leave the entire urethane adhesive bead on the pinch weld and allow a dry fit of the replacement glass.
NOTE: Lubricate the urethane adhesive with water to aid the Deluxe Windshield Removal Tool when cutting the urethane adhesive.
NOTE: Locating tabs need to be cut through in order to remove the rear quarter window glass. The new rear quarter window glass will be equipped with new locating tabs.
NOTE: Support the glass to prevent the glass from dropping while cutting the urethane adhesive.
Using the Deluxe Windshield Removal Tool, cut the urethane adhesive from the quarter window glass starting at the upper center of the quarter window glass and working toward the bottom corners.
5. Using the Deluxe Windshield Removal Tool, cut the remaining urethane adhesive and carefully remove the quarter glass from the vehicle and place on a stable work surface.
Installation
1. Dry fit the rear quarter window glass in the window opening.
- Position the quarter window glass on the pinch weld.
- Center the quarter glass in the opening for best fit.
- Make alignment marks with tape or non-staining grease pencil on the quarter window glass and the body.
2. After the dry-fit alignment, remove the glass from the opening and place on a stable work surface with the interior side of the glass facing upward.
3. WARNING: Repair any corrosion found on the pinch weld. The pinch weld is a structural component of the vehicle. Corrosion left unrepaired may reduce the structural integrity of the vehicle. Failure to follow this instruction may result in serious injury to vehicle occupant(s).
NOTE: Avoid scratching the pinch weld. Repair all minor scratches or exposed metal on the pinch weld following manufacturer's instructions. Use the same brand pinch weld primer, glass primer and urethane adhesive.
Using an appropriate tool, trim the urethane adhesive leaving a 1 mm to 2 mm (0.04 in to 0.08 in) base of original equipment urethane adhesive on the pinch weld.
4. Using a clean shop towel, brush or oil-free compressed air, clean the pinch weld area around the existing urethane adhesive. Remove any foreign material or water that may have entered during glass removal.
5. If reinstalling the original quarter window glass, remove the excess urethane adhesive from the glass leaving a thin layer to bond with the new urethane adhesive bead.
6. Clean the inside of the new quarter window glass with glass cleaner.
- Make sure to thoroughly clean the surface of the blackened border area where the urethane adhesive will be applied.
7. NOTE: Be sure to use the same brand and cure-rate products for the urethane adhesive and glass primer. Do not mix different brands of urethane adhesive and glass primer. Refer to the Material Chart in this procedure.
If installing a new rear quarter window glass, apply glass primer according to manufacturer's instructions. Allow at least 6 minutes to dry.
8. Cut the urethane adhesive applicator tip to specification.
9. NOTE: Use either a high-ratio, electric or battery-operated caulk gun that will apply the urethane adhesive with less effort and continuous bead.
NOTE: The rear quarter glass must be positioned within 10 minutes of applying the urethane adhesive.
Use caution when applying urethane adhesive. Apply to the outside edges of the locating tabs on the glass surface. Start at the bottom and work around to the sides of the rear quarter window glass.
- Make sure there are no gaps in the urethane bead.
10. WARNING: Do not drive vehicle until the urethane adhesive seal has cured. Follow urethane adhesive manufacturer's curing directions. Inadequate or incorrect curing of the urethane adhesive seal will adversely affect glass retention. Failure to follow these instructions may result in serious injury to vehicle occupant(s).
NOTICE: Before positioning the quarter window glass, open vehicle windows to prevent the air pressure of closing doors from affecting the urethane adhesive bond.
Using the alignment marks made previously, position the quarter window glass on the pinch weld.
11. NOTE: The urethane adhesive must cure for a minimum of one hour before testing for air and water leaks.
After the urethane adhesive has cured, check for water leaks and add urethane adhesive where needed.
12. Install the wiring harness brackets.
13. Install the rear quarter trim panel.
14. Clean the exterior and interior of the quarter window glass with glass cleaner.
