My window wont come up

You need to take the inner door panel off on the door where the window doesn't go up. Once off while looking inside the door operate the window to see if it just came off track from hitting hard bump or if something in the tracks or the regulator itself went bad. It may of just came off track and needs to be put back on and adjusted, if it was loose in the tracks hitting the bump hard could of made it jump off track.

it's the rubber band
