SUBJECT: WIND NOISE AT STATIONARY VENT WINDOW
MODELS AFFECTED: 1987-1988 ALLANTES
Some 1987-1988 Allantes may experience a wind noise at the stationary vent glass. The noise level will increase as vehicle speed increases. This condition may be caused by the lack of adhesive sealer between the vent frame and vent glass. To repair this condition, use the following service procedure:
1. Open door to its full open position.
FIGURE 1 - APPLYING LIQUID SOAP:
2. Apply a liquid soap bubble solution to the exterior of the vent frame and glass assembly where the glass and frame meet, refer to Figure 1.
FIGURE 2 - APPLYING COMPRESSED AIR:
3. Using a regulated air gun (at 30 psi), blow air from inside the vent frame and direct air flow towards perimeter of the vent frame, refer to Figure 2. Bubbles will appear on the outside of the vent glass in the area(s) not sealed.
CAUTION: To minimize the chance of personal injury, safety glasses should be worn when operating an air gun.
4. Clean the inside surface of glass and vent frame in the area to be sealed with isopropyl alcohol or equivalent.
FIGURE 3 - APPLYING MASKING TAPE:
5. Apply a strip of 3/4" masking tape on both the vent frame and vent glass for clean up purposes, refer to Figure 3. Apply tape as close as possible to the gap to be sealed in order to limit the bead size of the sealer.
6. Prepare area to be sealed using the two-step priming process included in adhesive caulking kit, P/N 9636067. Allow to dry for five minutes.
FIGURE 4 - APPLYING ADHESIVE CAULKING:
7. Apply a thin bead of GM black adhesive caulking, PN 9636067, in the affected area, refer to Figure 4.
8. Remove tape and allow adhesive to dry.
For warranty purposes use Labor Operation T6290 at .5 hour for sealing right side vent glass to vent frame and Labor Operation T6291 at .5 hour for sealing left side vent glass to vent frame.
