I assume you mean the front passenger side window and not both front and back, correct?
Does it make any noises when you try to operate the window? If you hear the motor working and nothing is happening, it may be the actuator arm. If you don't hear anything, the motor and/or one of the switches is bad.
If the window doesn't work from either the driver's side or passenger side switch, it's probably the motor is shot or a short circuit.
If it doesn't work from the driver's side but does work from the passenger side, the driver's side switch is shot. If it doesn't work from the passenger side but does work from the driver's side, the passenger side switch is shot.
The service manual can help you find the fault. Here's a link to the manual, broken up into sections. GW.pdf is the one for the windows, but the manual references various other sections depending on which part needs replacing.
