MODELS/YEARS 1985 NINETY-EIGHT
SECTION: 10
The following information is being provided to assist dealer personnel in the correction of wind noise comments on some 1985 Ninety-Eight models.
The vehicle may have to be road tested to locate the wind noise.. Useful tools in detecting the source of a wind noise are a powder gun, ultrasonic leak detector or a stethoscope.
FIGURE 1:
Figure 1 shows two areas that should be checked for wind noise. The following pages contain items within those areas and procedures to correct wind noise.
FIGURE 2:
Area 1 - Item 1
Center Pillar-to-Side Roof Rail - Joint Not Fully Sealed (Figure 2)
1. Remove center pillar trim panel.
2. Loosen roof drip scalp molding and retainer.
3. Carefully remove center pillar applique retaining nuts and applique.
4. Carefully pull back roof drip scalp molding and retainer to access joint area.
5. Joint area may be resealed using 3M No. 08531 Heavy Drip Check Sealer, 3M No. 08578 Strip Caulk (or equivalent). See Figure 2, View A.
6. Reinstall all previously removed items. Make sure that the center pillar applique mounting holes and opera lamp hole (if so equipped) are properly sealed prior to installation of the applique.

Area 1 - Item 2
Door Weatherstrip
The rear upper corner of the door weatherstrip should conform to the contour of the door frame. It should not be seated forward or low (shown by broken line in Figure 3), as this would increase the chance for marginal weatherstrip-to-body contact.
FIGURE 4:
Area 1 - Item 3
The rear leg of the front door frame should contact the bumper on the lock pillar or center pillar garnish molding with the door in the closed position. Contact should not be so great to increase door closing efforts. See Figure 4.
FIGURE 5:
Area 1 - Item 4
The door weatherstrip should be sealed to the door assembly as indicated by the arrows in Figure 5. The weatherstrip should be sealed from an area below the lock opening to the upper hinge using 3M No. 08011 Weatherstrip Adhesive (or equivalent) as shown in Figure 5, View A.
Area 1 - Item 5
Rear Door Weatherstrips - Sedan Styles
Make sure that the weatherstrip on the rear door is properly installed and cemented to the door. Check weatherstrip contact to body surfaces to insure a good seal.
FIGURE 6:
Area 2 - Item 1
Door frame-to-innner panel reinforcement areas (with mirror and "patch" removed) should be sealed with 3M No. 08578 Strip Caulk (or equivalent) as the shaded areas indicate in Figure 6, View A.
FIGURE 7:
Area 2 - Item 2
Air Leaks at Front Inboard Leg of Run Channel to Glass
This item can be revised by installing a length of weatherstrip shim material to the cavity as shown in Figure 7. The material to be installed, Dominion Sure Seal part no. RRR 1/4 or equivalent, should be 155 mm (6-1/8") in length and installed 30 mm (1-3/16") from the bottom edge of the run channel inboard leg. This material should be cemented into place using 3M No. 08011 Weatherstrip Adhesive or equivalent.
FIGURE 8:
Area 2 - Item 3
Door upper frame-to-inner panel seams should be sealed with 3M No. 08531 Heavy Drip Check Sealer (or equivalent), as indicated by the shaded area in Figure 8.
FIGURE 9:
Area 2 - Item 4
Air leaks which have been determined to come from the windshield area can be resealed using Urethane Adhesive, GM part no. 9636067 (or equivalent). The lower corner of the windshield can be the source of noise and additional sealant should be applied in the area shown in Figure 9, View A.
FIGURE 10:
Area 2 - Item 5
The door weatherstrip should be sealed to the door assembly as indicated by the arrow in Figure 10. That is, from an area even with the upper door hinge to the lower edge of the lock opening by using 3M No. 08011 Weatherstrip Adhesive (or equivalent) as shown in Figure 10, View A.
