Test Drive Evaluation

Attempt to define the general location of the wind noise source with the unaided ear and determine if the noise is of a loud, generalized background nature (wind rush) and/or a specific, localized nature (wind leak). Using a stethoscope, check:





1) perimeter of windshield (Figure A):

2) perimeter of fixed glass;

3) perimeter of dropping glass (all doors) (Figure A, B) :

4) primary door seals from front belt up around to rear belt; and

5) perimeter of backlite (Figure B).

Record problem areas and relative intensity level. Return to the service area and refer to diagnostic tree on the following page.

Note:
Sound levels at the ends of door inner belt weather seal, the dropping glass at the top of the center pillar and the windshield along the front pillar are generally higher than other locations when heard through the stethoscope. It is a judgement call as to whether the levels are significantly higher than normal and require corrections.
