When this happened to me, it turned out to be a combination of the window switches. Both the driver's switch and the switch on the rear door did not close a circuit, i replaced both from the scrapyard fixed the problem. If the window is stuck down and you need to pull it up in a hurry, do this:
pull the door panel off...unplug the motor from the harness (red wire about 5" long connected to motor)
The plug has two terminals...get a 12v power source, like a battery charger. Take the small + and - clips, connect the + side (red) to one terminal on the harness, and the - (black) to the other.
+ or - does not matter, it will either send the window up or down. If + and - sends the window down, just reverse it (- and +) and the window goes up.
However, if all connectoins were checked and the charger functions properly and the motor does not respond at all, the motor is the problem.
