Back Window Glass: Service and Repair

Special Tool(s)

REMOVAL







1. Disconnect the heated back window electrical connector.
2. Remove the headliner.
3. Remove the package trim panel.







4. Use Interior Auto Glass Cut-Out Knife Kit to cut the urethane sealant; remove the back window glass.

WARNING: TO PREVENT GLASS SPLINTERS FROM ENTERING EYES OR CUTTING HANDS, WEAR SAFETY GLASSES AND HEAVY GLOVES WHEN CUTTING GLASS FROM THE VEHICLE.

NOTE: Lubricate the urethane sealant where it meets the glass with water to aid Interior Auto Glass Cut-Out Knife Kit when cutting the urethane sealant.







5. Trim the remaining urethane on the pinch weld to the specified thickness.
- Use the supplied wool applicator to apply Urethane Metal Primer to any exposed metal on the pinch weld.
- Add Urethane Sealant to bring the remaining urethane sealant to the specified thickness.
- If reusing the back window glass, remove all old urethane sealant with an alcohol-free glass cleaner.

INSTALLATION







1. Dry set the back window glass.
- Position the back window glass in the pinch weld.
- Align the back window glass from the bottom center point of the glass out to the two spacers at the bottom of the pinch weld.
- Align the gap of the back window glass at the top and sides of the back window glass edge to the pinch weld edge.
- Mark the back window glass and the body when aligned as specified.
- Remove the back window glass from the pinch weld and clean the back window glass inside the perimeter with an alcohol-free cleaner and wipe the edge of the glass with a clean cloth.

NOTE: Keep glass and body surfaces free of dirt, water, and oil. Do not touch coated surfaces with your hands.







2. Install the back window glass moulding on the back window glass perimeter.
- Apply (A) Urethane Metal Primer to the back window glass moulding. Allow ten minutes drying time.
- Apply (B) Urethane Glass Primer to the back window glass.







3. Apply Urethane Glass Prep as shown, and repeat the application.
- Apply Urethane Glass Prep on the back window glass directly inside the back window glass moulding on the blackout ceramic coating.
- Immediately wipe off the Urethane Glass Prep.
- Repeat the Urethane Glass Prep application.

NOTE: Immediately wipe off the urethane glass prep after application because it flash dries.







4. Apply Urethane Glass Primer as shown.
- Apply Urethane Glass Primer around the entire outer edge of the inside of the back window glass directly inside the back window glass moulding.
- Allow ten minutes drying time.

CAUTION:
- If primer gets on your hands, remove it immediately.
- Do not apply the urethane glass primer inside of the blackout ceramic coating. The primer will permanently discolor the back window glass.







5. Cut the nozzle of the urethane sealant canister to specification.







6. Apply a bead of Urethane Sealant around the circumference of the glass.
- Ensure that the bead of Urethane Sealant is smooth and even. If necessary, reshape the bead with a suitable tool, taking care not to trap air in the bead.

CAUTION:
- Use only Urethane Sealant to repair water and air leaks in the urethane sealant.
- After replacing the urethane installed glass, the vehicle should not be driven until the urethane has cured. The curing times at temperatures above 13°C (55°F) and relative humidity above 50% curing time is 12-24 hours (decreasing at higher temperatures and lower humidities). Refer to the detailed instructions provided by the manufacturer in the kit. Inadequate curing of the urethane may adversely affect the strength of the urethane sealant bond.







7. Use the alignment marks to install the back window glass.

CAUTION: Open the windows to prevent the back window glass from being pushed out by air pressure if a door is closed.

NOTE: Ensure that Urethane Metal Primer is clean and dry.

8. After the Urethane Sealant has cured, check for water leaks and add Urethane Sealant where needed.

CAUTION:
- Use only Urethane Sealant to repair water and air leaks of the urethane sealant.
- After replacing the urethane installed glass, the vehicle should not be driven until the urethane has cured. The curing times at temperatures above 13°C (55°F) and relative humidity above 50% curing time is 12-24 hours (decreasing at higher temperatures and lower humidities). Refer to the detailed instructions provided by the manufacturer in the kit. Inadequate curing of the urethane may adversely affect the strength of the urethane sealant bond.
