I attached the wiring schematic below in pics 1 and 2. I overlapped them to help you follow them.
Now, first check to see if there is power out from the violet wire at the main switch when you select the up direction. That is what powers the window up. The power is sent via the violet computer data line to other windows. See attached. Remember, the power to raise and lower the window is controlled by reversing the polarity of the power supply. So, if it works down, that tells me that the wire isn't broken, but leads me to believe the switch is bad.
Let me know what you find.
