Condition
Some customers may comment that at combined vehicle and wind speeds of 80 km/h (50 mph) and above and with outside air temperatures of 24°C (75°
F) and above, a whistle type noise (similar to a train whistle) can be heard coming from:
^
On DeVille: The upper center windshield area.
^
On LeSabre: The windshield upper corner area.
Cause
This condition may be due to wind getting up underneath the trailing edge of the windshield reveal molding causing it to flutter/vibrate against the
DeVille roof panel and the LeSabre windshield pillar panel.
Correction
Fill the gap between the panel edge and the windshield reveal molding by applying a bead of urethane adhesive. Refer to the appropriate repair
procedure.
Buick Repair Procedure

Use a 50/50 mixture of isopropyl alcohol and water by volume on a dampened lintfree cloth to clean the area (4) underneath the trailing edge of
