HOW TO LOCATE WIND NOISES

M1421004200164

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.

4. When such a place is found, cover it again and repeat the 

procedure to check if there are any other noise source.

5. If no others are found, the last remaining tape is the only 

source.

6. Cut the remaining piece of tape into smaller pieces, attach it 

again as it was before, and then remove the pieces one by 
one to narrow down the source.
