IIRC all window controls on the driver's side door are run on the same fuse. If one works, they all work.

Probably a burnt out motor. Can you hear the motor trying to run? If so your problem is most likely a jammed/broken regulator. My guess is that you've just burnt out the motor though. They're not too expensive and pretty easy to replace. Check the DIY section for my write up

 

Take the panel off the door and check if voltage is reaching the motor when you press the button. If so, it would be a motor or regulator problem. If not, could be a bad switch or broken wires in the driver's door hinge area. Try opening the driver's door and shake the wires around while pressing the button.
