METHOD FOR MANUFACTURING A VEHICULAR REAR SLIDER WINDOW ASSEMBLY WITH RETAINING ELEMENT

A method for manufacturing a vehicular rear slider window assembly includes attaching an upper rail and a lower rail at an inner side of a fixed window panel. The lower rail includes a first attaching surface that attaches at the fixed window panel and a second attaching surface opposite the first attaching surface. The method includes disposing a movable window panel in a channel of the lower rail and a channel of the upper rail and attaching a retaining element along the lower rail and at the second attaching surface of the lower rail. The retaining element includes an attaching portion that attaches at the second attaching surface and a retaining portion that extends at least partially across the channel of the lower rail to limit vertical movement of the movable window panel relative to the upper and lower rails.
