Quarter Window Glass: Service and Repair

Quarter Glass Replacement

NOTE:

- Put on gloves to protect your hands.
- Wear eye protection when removing the glass with piano wire.
- Use seat covers to avoid damaging any surface.
- Do not damage the glass antenna grid lines and terminals.

1. Remove these items:

- C-pillar trim
- D-pillar trim
- Upper quarter window trim

2. Passenger's side: Disconnect the glass antenna connector (A).






3. If the old quarter glass is reinstalled, make alignment marks across the glass and body with a grease pencil.

4. Apply protective tape along the inside and outside edges of the body. Make a hole through the adhesive with an awl, from inside the vehicle. Push a piece of piano wire through the hole, and wrap each end around a piece of wood.

5. With a helper on the outside, pull the piano wire (A) back and forth in a sawing motion. Hold the piano wire as close to the quarter glass (B) as possible to prevent damage to the body, and carefully cut through the adhesive (C) around the entire quarter glass.






Cutting positions





6. Carefully remove the quarter glass.

7. If the old quarter glass is reinstalled, make the alignment marks (A) along the edges of the clips (B) with a grease pencil as shown.





8. Scrape smooth the old adhesive with a knife until there is a thickness of about 2 mm (0.08 in) on the bonding surface around the entire quarter glass opening flange:

- Do not scrape down to the painted surface of the body; damaged paint interferes with proper bonding.
- Remove the clips from the body.

9. Clean the body bonding surface with a sponge dampened in isopropyl alcohol. After cleaning, keep oil, grease, and water from getting on the surface.

10. If you are reinstalling the old glass, scrape off all of the old adhesive with a putty knife and the damaged clips from the quarter glass. Clean the bonding surfaces on the inside face and the edge of the quarter glass with isopropyl alcohol. Make sure the bonding surface is kept free of water, oil, and grease.

11. Attach the rubber dam (A) with adhesive tape to the inside surface of the glass (B) as shown:

- Be sure both ends of the rubber dam line up with the alignment marks (C).
- Be careful not to touch the glass where the adhesive is applied.





12. Attach the clips (A) with adhesive tape to the inside face of the quarter glass (B) as shown:

- Be sure the clips line up with the alignment marks (C) you made in step 7.
- Be careful not to touch the quarter glass where the adhesive is applied.





13. With a sponge, apply a light coat of glass primer to the edge of the glass (A) and along the rubber dam (B) as shown, then lightly wipe it off with gauze or cheesecloth:

- With the printed dots (C) on the quarter glass as a guide, apply the glass primer to the corner portions of the quarter glass.
- Do not apply body primer to the quarter glass, and do not get body and glass primer sponges mixed up.
- Never touch the primed surfaces with your hands. If you do, the adhesive may not bond to the quarter glass properly, causing a leak after the quarter glass is installed.
- Keep water, dust, and abrasive materials away from primed surfaces.





14. With a sponge, carefully apply a light coat of body primer to any exposed paint or metal around the flange where new adhesive will be applied. Let the primer dry for at least 10 minutes:

- Do not apply body primer to any remaining original adhesive on the flange.
- Be careful not to mix up the body and glass primer sponges.
- Never touch the primed surfaces with your hands.





15. Cut a "V" in the end of the nozzle (A) on the adhesive cartridge as shown.






16. Put the cartridge in a caulking gun, and run a continuous bead of adhesive (A) around the edge of the glass (B) as shown. With the glass primer (C) you applied in step 13 on the quarter glass as a guide, apply adhesive to the corner portions of the quarter glass. Apply the adhesive within 30 minutes after applying the glass primer. Make a slightly thicker bead at each corner.






17. Hold the quarter glass (A) over the opening, align it, and set it with suction cups (B) down on the adhesive. Lightly push on the quarter glass until its edges are fully seated on the adhesive all the way around.

NOTE: Do not open or close the doors for an hour until the adhesive is dry.





18. Remove the excess adhesive with a putty knife or a shop towel dampened with isopropyl alcohol.

19. Wait at least an hour for the adhesive to dry, then spray water over the quarter glass and check for leaks. Mark the leaking areas, let the quarter glass dry, then seal with sealant. Let the vehicle stand for at least 4 hours after quarter glass installation. If the vehicle has to be used within the first 4 hours, it must be driven slowly.

20. Reinstall all remaining removed parts.

NOTE: Advise the customer not to do the following things for 2 to 3 days:

- Slam the doors with all the windows rolled up.
- Twist the body excessively (such as when going in and out of driveways at an angle or driving over rough, uneven roads).
