bulletin.
Proper diagnosis may be made with a variety of tools and methods including stethoscopes, dust guns, sonic instruments, visual inspections, dollar bill
method and etc. It is important to remember that windnoise can best be described as air leaking from the 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 front door, auxiliary weatherstrips and door opening weatherstrips should be visually inspected for proper gaps, fits, weatherstrip
contact,, and sealing. The vehicle should also be road tested to determine the location and degree of windnoise/turbulence on the vehicle.
Some primary areas of windnoise may be:
1.
Upper "A" pillar door opening weatherstrip to door frame.

Front window run channel to door frame.
3.
