Chances are the problem is in either the window's tracks, the master switch (at the driver's armrest), the switch on the passenger side, or the window regulator and motor. All of these are easy to replace. If push comes to shove, then the most expensive part is the master switch.
First, make sure the child lock switch on the master switch is in the "up" position. Does the driver's side master switch operate the window? How about the passenger side switch?
Second, lube the window's tracks as shown here:
I like the WD-40 brand silicone lube that Scotty uses in the video. Home Depot has it. The nozzle rocks.
