# WIND NOISE AT FRT. DOOR WINDOW MAY BE MISSING CAULK SEALER

WINDNOISE AT FRONT DOOR WINDOW

#### VEHICLES AFFECTED 1987-1988 'E' MODELS -----------------

Some 1987-1988 Eldorados built after 1987 VIN breakpoint 610082 and prior to 1988 VIN breakpoint 603474 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 weather strip retainer and door come together. To repair this condition, use the following procedure:

1. With the window in the down position remove 8 to 10 inches of the glass the glass run channel weather strip from the forward vertical section, (i.e. mirror patch area). If the forward vertical section is removed, the metal retaining clips may damaged the mitered corner.

2. At the end of the weather strip retainer there is a step where the door and retainer meet. Add thumb grade (strip- caulk) sealer, 3M P/N 08578 or equivalent, as shown in Figure 2, views B and C.

3. Reinstall the glass run channel weather strip to the cavity of the weather strip retainer. IMPORTANT: Be sure that the weather strip is correctly seated as shown in Figure 1, Section B-B.
