Quarter Window Glass: Service and Repair
Installation
INSTALLATION
WARNING: Do not operate the vehicle within 24 hours of quarter glass installation. It takes at least 24 hours for urethane adhesive to cure. If
it is not cured, the quarter glass may not perform properly if the vehicle is in an accident.
CAUTION: To help prevent water leaks, partially roll down the left and right door glass before installing the quarter glass. This avoids
pressurizing the passenger compartment if a door is slammed before the urethane is cured.
CAUTION: Protect all painted and trimmed surfaces from coming in contact with urethane or primers.
NOTE: Grand Cherokee (WK) shown, Commander (XK) similar.
CAUTION: Roll down the left and right front door glass and open the liftgate glass before installing quarter glass to avoid pressurizing the
passenger compartment if a door is slammed before urethane is cured. Water leaks can result.
NOTE: To prevent corrosion, do not damage paint on the quarter glass fence when removing original urethane.
NOTE: The quarter glass fence should be cleaned of most of its old urethane adhesive. A small amount of old urethane, approximately 1 mm in
height should remain on the fence. Do not completely remove all old urethane from the fence, the paint finish and bonding strength will be
adversely affected.
1. Using a razor knife, level the original bead of urethane on the fence to a thickness of approximately 1 mm (0.04 in.).
2. If the quarter glass is being reused, remove as much of the original urethane as possible from the glass surface using a razor knife.
WARNING: Do not use solvent based glass cleaners to clean the quarter glass before applying glass prep and primer or poor glass adhesion
may result.
3. Clean the inside of the quarter glass with an ammonia based glass cleaner and a lint-free cloth.
4. Apply glass prep adhesion promoter 25 mm (1 in.) wide around the perimeter of the glass and 5 mm (0.2 in.) from the edge of the glass and wipe
dry with a clean lint-free cloth until no streaks are visible.
5. Apply glass primer 25 mm (1 in.) wide around the perimeter of the glass and 5 mm (0.2 in.) from the edge of the glass. Allow at least three minutes
drying time.
6. Using a flashlight, verify that the primer is completely and evenly installed along the perimeter of the quarter glass.
7. Re-prime any area that is not fully and evenly primed.
8. Clean the quarter glass fence with an ammonia based glass cleaner and a lint-free cloth.
9. Apply pinch weld primer 15 mm (0.75 in.) wide around the quarter glass fence. Allow at least three minutes drying time.
10. Using a flashlight, verify that the primer is completely and evenly installed along the quarter glass fence.
