WIND NOISE/WHISTLE NEAR WINDSHIELD (RE-SEAL OPENING)

SUBJECT: WIND NOISE (WHISTLE) FROM FRONT OF VEHICLE NEAR WINDSHIELD (SEAL OPENING) (Revised to include Fig. 1)

VEHICLES AFFECTED: 1991 "L" CAR

Condition:

Owners of some 1991 L Coupe and Sedan models may comment on a wind noise (whistle) coming from the front of the vehicle near the windshield under normal driving conditions.

Cause:

During assembly of the shroud upper panel to the dash panel, some welds were mislocated and sealer applied incorrectly. This created a narrow opening between the two panels on the left hand (driver's) side allowing air to pass through and create the wind noise (whistle).

Correction:

Seal opening between shroud upper panel and dash panel using the following procedure:

1. Remove the left (driver's side) shroud top vent screen using the procedure in the Service Manual.

2. Seal the area where the shroud upper panel and dash panel come together using 3M strip caulk #08578. Amount of material used not to exceed six strips. Refer to Figure 1 to identify the exact location of the area to be sealed.

Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.
