Your drivers side switch is a master switch for the rest of the doors. Inbetween the door jam is a plastic/rubber tube that contains a wiring harness.

The wires in this harness frequently get cracked and broken. (From the door being constantly opened and closed, especially in cold weather)

If you're handy with a digital multi-meter, then you can probe these wires for continuity. What you'll do is first take off the switch from the door. Then unplug the connector. Then connect the positive lead of the meter to the ground side of the fuse for you window circuit. Then use the negative lead to probe each wire that goes to your switch. (The one for the main/drivers window)

If there's no continuity for one of those wires, then you narrow down where the break is by poking the negative lead through the wire until there is continuity. That's where your break is. Just splice in a new wire.

If you aren't handy with a meter, then you'll have to take it into a shop.
