Saturday night was cold and snowing, my girlfriend got into are 2011 s40 t5 and put the driver window down. Well tried to. The window now doesn't go up or down. I can move it myself but that's all. What do I need to replace to get this fixed. Also I do most of the work myself. Any help would be much appreciated thanks. P.s. the window switch does move the track up and down just not the window.
