INTRODUCTION:
If a creak, tick, or rattle noise is heard at the top or bottom of the windshield, the source of the noise may be the two windshield stoppers bonded to the top of the windshield or the windshield retainers bonded to the lower edge of the windshield. This bulletin provides the recommended repair procedure to eliminate these types of noises from the windshield area.

NOTE:
Some vehicles have both stoppers and retainers while others may only have stoppers at the top of the windshield/rear glass. Use the chart in this bulletin to determine the location of the windshield/ rear glass locating pins.

REPAIR PROCEDURE:

Upper Windshield Glass Stoppers:







1. Remove both sun visors and both A-pillar garnishes, and then carefully lower the front of the headliner to gain access to the windshield stoppers (refer to the appropriate model year Repair Manual for the proper procedure).

NOTE:
It is very important that the front of the headliner be lowered carefully and slowly. Applying too much downward force on the headliner will cause it to develop a permanent crease in the surface material.

The stoppers are located on the inside the passenger compartment behind the windshield glass blackout section (near the top front edge of the metal roof opening). The stoppers are typically located 20 - 25 cm (7.9 - 9.8 in.) inboard of the top corners of the windshield glass.







2. Cut OFF the tip of the plastic stopper as shown in Figure 3.

HINT:
It is sometimes necessary to bend the metal body tab down to gain access to the shaft of the stopper.







3. Once the tip of the stopper has been removed, use a screwdriver to open a gap between the roof panel and the remainder of the plastic windshield stopper.

NOTE
Apply tape to the screwdriver tip before use to prevent scratching.

4. Test drive vehicle prior to reassembly to confirm that the noise has been eliminated.
5. Reassemble the vehicle.

Lower Windshield Retainers:







1. Carefully remove the plastic cowl cover at the base of the windshield and store it in a safe location for reinstallation later (refer to the appropriate model year Repair Manual for the proper procedure).
2. Locate the lower windshield retainers.







The retainers are typically located 140 - 200 mm (5.5 - 7.9 in.) inboard of the lower corners of the windshield. The flat portion of the retainer is adhered to the backside of the windshield with double-sided, foam-backed tape.







3. Use a "Mini" Hacksaw with a fine tooth 10-inch blade to cut OFF the pin portion of the glass retainer flush with the flat portion of the windshield retainer (diagram shows the windshield retainer location to cut off the plastic pin).
4. Test drive the vehicle to confirm the elimination of the noise.
5. Reassemble the vehicle.

Rear Upper Glass Stoppers
1. For removal of Rear Upper Glass Stoppers, refer to Step 1 of Upper Windshield Glass Stoppers.
