Customer comments regarding wind noise may be addressed by using the procedures on the individual items listed in this bulletin. Proper diagnosis may
be made with a variety of tools and methods including stethoscopes, dust guns, sonic instruments, visual inspections, dollar bill method etc. It is
important to remember that wind noise can best be described as air leaking from inside of the vehicle outward while traveling at highway speeds.
Turbulence or wind rush is best described as air passing over and around body openings and moldings.
Prior to any repairs, the front and rear door auxiliary weatherstrips and door primary opening weatherstrips should be visually inspected for proper gaps,
fits, weatherstrip contact, and sealing. The vehicle should also be road tested to determine location and degree of wind noise/turbulence on the vehicle.
