Hi,
You should first determine if the window switch (centre console) is sending power to the door motor, in the "UP" position.
If the motor is 'trying' to operate (i.e. you can hear the motor click when switch is UP), then the glass may simply be jamming in the tracks, or needs adjusting on the regulator rail.
I would recommend you buy some Graphite Powder and springle it down both the inner/outer tracks to lubricate.
If no power is evident to the motor, then you should suspect bad (or damaged) contacts inside the switch.
If you're unsure about the switch but confident enough to remove the inner door card/panel, then you can try connecting each of the window motor "wires" to a terminal of another car battery - this will manually operate the window motor. Then, connect to opposite battery terminals to power the motor in the opposite direction.
If the window motor proves faulty, then obtain you could obtain a 2nd hand electric door regulator from your local auto wrecker.
Cheers,
