As mentioned by @kdefilip, the window switch is in series, so any issue with any switch will disable the whole circuit.
Since you're hearing stuff happen when you press the switch, I'd hazard a guess that the regulator or transmission needs attention. The regulator has a spring to neutralize the weight of the window so the motor just has to move it, and the transmission is where the motor uses a worm gear to turn a 'normal' gear, which results in a reduction of the gear ratio. The worm is usually metal and the gear is usually plastic, so it's possible that it has stripped out.
Both of those will require you to pull the panel and do some inspecting.
