There are a multitude of reasons for it to not work . Start with the one that usually fixes the problem . Check the wiring between the door and the body . the act of opening and closing the door eventually wears the wiring to the point of breaking . So check the wires here first . There are fuses in the panel that are for the windows check then next . Then with a multi meter check that the power is getting to the switch . If all the windows have failed on the drivers door but work at the other switches the problem could be the drivers panel ground or the switch itself could be faulty . Test it with your multi meter. Seeing how all the windows are effected its safe to say its not the window motors. Just a few things to check . Hope this helps
