Interior wind noise is not heard when the window is lowered. Interior wind noise is caused by the air leaving the inside of the vehicle through a seal or a seam.

1. Mask off the body ventilation outlets to cause added air pressure within the vehicle.
2. Test drive the vehicle and listen for wind noise or a whistle.
3. Pull the vehicle over and make the temporary repairs using masking tape. If you cannot determine the source of the wind noise, perform one or more of the following diagnostic tests:

• | Tracing Powder or Chalk Test.

• | Air Pressure Test.

• | Soap Suds or Bubble Test.
