What about the ground wire? Check the voltage on the power window motor's connector, but that has to be done with it plugged in. If the ground circuit is open, you will find twelve volts on both motor wires regardless which way the switch is pressed.
Those two motor wires can be found at the switch too, but without digging up a wiring diagram, I do not know what the wire colors are. The clue is you should have twelve volts on one wire only, then, when the switch is pressed, you should have twelve volts on a second wire. If the ground circuit is open, you will find twelve volts on all of the wires at the switch.
