Interior Wind noise

Warning: Refer to Assistant Driving Warning in the Preface section.

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. Tape over the relief valves 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:

•	Air Pressure Test

•	Soap Suds or Bubble Test

•	Tracing Powder or Chalk Test
