Abstract: A sliding window assembly for a vehicle includes first and second fixed window panes spaced from each other defining an opening therebetween. A sliding window pane is moveable relative to the first and second fixed window panes for covering and uncovering the opening. First and second tracks are spaced from each other and are connected to the first and second fixed window panes. The first and second tracks are coupled to the sliding window pane for guiding movement of the sliding window pane relative to the first and second fixed window panes. The first track and the second track are rigidly interconnected only by the first and second fixed window panes.
