well, my passenger side window didnt work for a while, but you could here the motor running. I took off the door panel, and the lifting arm under the window lost the bolt which attaches it to the bottom of the window. So I took a zip tie and re-attached the arm to the window. Just take off your door panel and see whats wrong, we need more details to be able to help you
there should be holes in the frame of the door, after you take of the inside door panel. There may be plastic glued to cover these holes, just pull that away and take a look. The lifting arm is white plastic, and you may have to look through the holes at different angles to see it(not sure if your window is up or down right now). However, the track which the window follows on its longest vertical side(the left side when looking at it from inside the car), may have also came loose if the arm is not attached right. Just PM me and I'll try to help as much as possible.
