How do I take away inside of door to reach electric window?

did drive on a bendy and hilly road, worst ever you can think and car made noises everywhere,,and then window stopped working on drivers side,
engine runs,,but it sounds as if the glaze has popped out of postion and I do not want top use or even try the button since it is noisy and I think I might damage,,how do I take away the inside of the dorr so I can have a look to see if there is something I can do myself ?
