Some 2021-2022 F-150 vehicles equipped with a B and O�® audio system may exhibit the rear window glass sliding panel rattling when in the open position and music is playing. This may be due to a low amount of seal extrusion pressure provided by the rear window glass sliding rail and/or the rear window glass sliding panel defroster wire harness vibrating between the two panels of glass. To correct the condition, follow the Service Procedure to install the rear window glass sliding panel service kit.
