HOW TO LOCATE WIND NOISES

M1421004200067

1. Attach cloth tape to every place, such as panel seams,

projections, molding seams, glass and body seams, etc.
which might conceivably be the source of wind noise.

2. Then make a road test to check that the places not covered

by tape are not sources of wind noise.

3. Remove the strips of tape one by one, making a road test

after each is removed, until a wind noise source is
discovered.
