Are you speaking of the window that is located on the roof in the rear of the car? or the Window located in the upper half of the rear door/hatch.If you are talking about the roof then take it back to the person who fixed it as this is supposed to open but only from the inside.If you are speaking of the one on the rear door this one never did open and there is no way it can. The rear clam shell door had an upper and lower half but the glass was never designed to open independently from the frame of the Element.Hope this helps
