Caution : An assistant should drive the vehicle while the technician checks for the location of the windnoise, in order to prevent personal injury or vehicle damage.

A test drive in the vehicle is necessary to accurately determine the location of the windnoise. Often there is a primary leak and secondary leaks. Failure to repair all leaks will only reduce the windnoise, not eliminate it.
During the test drive the technician should bring the following items to aid in determining the location of the windnoise.
Perform the following steps in order to conduct the road test:
  1. Choose a route that includes smooth straight streets that run in all four directions (north, south, east, and west).
  2. Choose a route that includes smooth straight streets that run in all four directions (north, south, east, and west).
  3. Choose streets with little traffic or noise that would interfere with the test.
  4. Drive the vehicle at the speeds at which the noise was noticed by the customer or until the noise is produced. Do not exceed legal speed limits.
  5. The windnoise is external if any of the following conditions occur:
  6. Internal windnoise is air leaving the vehicle and should be repaired in the following manner.

Windnoise Repair

Windnoise leak repairs are very similar to waterleak repairs. Refer to Section 9I, Waterleaks.The actual procedure depends on the type of seal being repaired.
Leaks around the door opening weatherstrips do not always indicate a faulty weatherstrip. A door or window adjustment may resolve the condition. Refer to Section 9P, Doorsor Section 9L, Glass and Mirrors.
