I just wanted to double check year--make--model? It's probably the window motor, but, I'd still check wiring circuits.

If your driver side works, it is not the relay or the ETACS unit.
As Stealthee has suggested check the window lock button.
When you press the window up and down switch in both directions, do you hear any motor load?
If you do than the switches are probably good but may also suggest high resistance in the contacts of the switch(es).
If not, the possibilities are the driver side switch, passenger side switch, motor or wiring between components.
You will need to remove the passenger door panel to check.
As long as you don't suspect the driver side switch, you do not need to pop the driver side door panel.
You can check the driver side operation from the passenger side.
Check with a voltmeter at the passenger switch (all readings taken from passenger switch assembly) with both switches at rest you should get the following readings:

Green/Yellow = Ground
Blue/Black = +12V
Brown/Yellow = Ground
Green/Red = Ground
Green/Black = Ground

If you operate the passenger window in the up direction from the driver side switch:

Green/Yellow = Ground
Blue/Black = +12V
Brown/Yellow = +12V
Green/Red = +12V
Green/Black = Ground

If you operate the passenger window in the down direction from the driver side switch:

Green/Yellow = +12V
Blue/Black = +12V
Brown/Yellow = Ground
Green/Red = Ground
Green/Black = +12V

If you don't get ground on any wire, the possibilities are the driver side switch or wiring.
Lack of +12V on Blue/Black would suggest an open in the the wire.

Operating the passenger side switch, up:

Green/Yellow = Ground
Blue/Black = +12V
Brown/Yellow = Ground
Green/Red = +12V
Green/Black = Ground

Operating the passenger side switch, up:

Green/Yellow = Ground
Blue/Black = +12V
Brown/Yellow = Ground
Green/Red = Ground
Green/Black = +12V

If either or both of the Green/Red or Green/Black wires do not change state when the switch is operated, the passenger switch needs replacing.

Disconnect the plug for the passenger switch and apply +12V to Green/Red and ground to Green/Black.
You window should rise if the motor is good.
If not, your motor is most likely bad.
If you hear motor load when you apply direct power but the window does not go up, check to make sure the regulator is not binding up.

As a last resort, remove the motor, push the window up by hand and reinstall the motor.
This doesn't fix anything but will keep your interior from getting wet in the rain.

You do not have the follow the above in order, I wrote it as it came to me. So you can check the motor first.

Let us know how it goes.
