You'll need to provide some more information to us at this point. Specifically:
1. Can you measure voltage at the output of the switch on the pass. window switch in the drivers door? If you cannot, then you could have a bad connection at the termination point of the wire to the switch itself. If you can, then you need to move on to the passenger door.
2. Can you measure voltage at the INPUT side of the passenger switch when pressing the pass window switch in the drivers' door? If not, then somewhere between the switches, the connection is broken. (I would then look in the kick panel area for the molex plugs that connect the door harnesses to the vehicle main harness and inspect them for a bad connection, etc.)
3. If you can measure input voltage at the switch in the pass door, can you measure output voltage at the switch in the pass door? If not, then inspect the connection point here.
It is simply a process of elimination. Your power window motors are simple - put 12 volts to one wire, ground the other and the motor will move one direction. Reverse the connections, and the motor will move in the opposite direction. To get the window UP for now, you can do this with a battery from a cordless drill (at least a 9.6 volt) by unplugging the motor and temporarily connecting it to the cordless drill battery.
