Power window motors are operated via two circuits; power and ground. The unique part about these circuits is that the direction that the motor rotates (moving the window up or down) is controlled by the direction of current flow using window switches. Window switches are all grounded in their default position but when they are moved to the UP or DOWN position they are connected to power instead. Here's how this works: when the master switch's right-front window switch is held to the UP position, the UP circuit is removed from ground and power flows through it, then passes through the UP circuit of the right-front window sub-switch, then to the window motor, then makes it's way through the DOWN circuit through the right-front sub-switch, then the master window switch, then to the common ground. When the master switch's right-front switch is held to the DOWN position, the DOWN circuit is removed from ground and power flows through it to the sub-switch, then to the window motor, then makes it's way to the common ground through the sub-switch and master switch's UP circuit. For your specific case I'd suspect that the master window switch's right-front switch connection to the DOWN circuit is not grounding by default like it should and therefore not providing a ground path for the motor when the UP circuit is energized.

Your window won't work for one of 3 reasons, 1. fuse is blown 2. Window switch is bad 3. Window motor is bad. To get the window up, Take off door panel remove window mechanism(metal piece with teeth on it) from motor and then you can push window up(window will not stay up unless you duct tape it or reconnect to motor.
