SUBJECT: WINDNOISE AT FRONT DOOR WINDOW - OUTSIDE MIRROR AREA
MODELS AFFECTED: 1987-1988 RIVIERA
Some 1987-1988 Rivieras built after 1987 VIN breakpoint 441555 and prior to 1988 VIN breakpoint 402080 may experience a windnoise condition at the mirror section of the front door windows. This may be caused by the omission of thumb grade (strip caulk) sealer at the step where the glass run channel weatherstrip retainer and door come together. To repair this condition, use the following procedure:
FIGURE 1:
1. With the window in the down position remove 8 to 10 inches of the glass run channel weatherstrip from the weatherstrip retainer, as shown in Figure 1.
NOTICE: Do not attempt to remove the glass run channel weatherstrip from the forward vertical section, (i.e. mirror patch area). If the forward vertical section is removed, the metal retaining clips may damage the mitered corner.
FIGURE 2:
2. At the end of the weatherstrip retainer there is a step where the door and retainer meet. Add thumb grade (strip-caulk) sealer, 3M Part Number 08578 or equivalent, as shown in Figure 2, views B and C.
FIGURE 1:
3. Reinstall the glass run channel weatherstrip to the cavity of the weatherstrip retainer. IMPORTANT: Be sure that the weatherstrip is correctly seated as shown in Figure 1, Section B-B.
