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.
Some vehicles have both stoppers and retainers while others may only have stoppers at the top of the windshield. Use the chart in this bulletin to determine the location of the windshield holding devices.

Repair Procedure
Windshield Stopper Repair
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).
NOTICE
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 of 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 the illustration.
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.
4. Test drive vehicle prior to reassembly to confirm that the noise has been eliminated.
5. Reassemble the vehicle.
Windshield Retainer Repair:
1. Carefully remove the plastic cowl top ventilator louver 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 windshield retainers at the lower edge of the windshield.
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 (see Figures 9 & 10 for pin location).
4. Test drive the vehicle to confirm the elimination of the noise.
5. Reinstall the plastic cowl top ventilator louver(s).
