Usually it's either the window regulator or window motor. You can buy both online for about half of what the dealer will charge for the part. It could also be the master switch on the driver's side, but if all the other windows are working fine, I'd replace the regulator and motor. I bought the regulator with motor combo for $81 delivered recently and my window is working perfectly now.
