Customer comments regarding WINDNOISE may be addressed by using the procedures on the individual items listed in this bulletin. Proper diagnoses
may be made with a variety of tools and methods including stethoscopes, dust guns, sonic instruments, visual inspection, dollar bill method, etc. It is
important to remember that windnoise can best be described as air leaking from inside of the vehicle outward while traveling at highway speeds.
Turbulence or Windrush is best described as air passing over and around body openings and moldings.

Prior to any repairs, the door primary opening weatherstrips should be visually inspected for proper gaps, fits, weatherstrip contact and sealing. The

Windshield side reveal gap to door.
