Some customers may comment on wind noise coming from either of the body side quarter windows while driving with the quarter windows closed. The wind noise may be more noticeable at speeds over 56 km/h (35 mph).
An insufficient seal of the window frame to the body or an improper window latch length may cause this condition.
A new body side quarter window kit is available to correct this condition. This window kit includes the window frame and glass, three frame centering screws that reinforce the sealing of the window frame to the body, and an instruction sheet. The window frame also features a reinforcement latch tab to improve latch efforts and function.
Replace the applicable body side quarter window on affected vehicles. Use the appropriate part number listed below.
Refer to the applicable Service Manual for quarter window removal and additional installation procedures. Also refer to the instruction sheet provided with the window kit for installation information.
