FYI, the window fuses are under the hood on the firewall. The windows are on the circuit diagonally, that is: Left Front and Right Rear on one fuse, Right Front and Left Rear on another. What you're describing sounds like a blown fuse. Are you sure the front pass went up and down yesterday, when the driver's rear didn't? Otherwise, it may be a bad wire in the door panels, or a loose contact at the motor.
