Get a 18V drill with phillips screw extention and start buzzing the screws in the armrest and under out...the glass could be anywhere so wear gloves.
Good Luck

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door

SOURCE: window motor any histories of problems

electric window motors are known for failing, but so are the switches... a good indicator is if it is the motor than while sitting in the car and holing the switch down hit of punch the door trim in the centre, not had enough to smash the door trim but enough to shock the electic motor, if the window starts to work then the motor is the most likley fault.
If this doesn't work the door trim will need to be removed, when removed disconnect the wiring to the window motor, reconnect the window switches and check for power ot the harness to the motor while operating the switch. if not power supply to either wire in the down and up position of the switch, then most likley the switch.
I f there is power at these wires when the switch is operated then the motor must be at fault.
Good luck
