Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.In order to be able to help you with this I need to know which window your referring to please. While you checking this check and see if you have battery voltage at the motor while corking the switch up and down with it plugged in. Check this and post back with complete information and we can work from there.
If you getting battery voltage at the motor and a good ground while trying to operate it and the motor dose not move then that usually means the window motor/module is failing. See the wiring diagram in the link below for reference. Take a look at the diagram and check to be sure you have a ground at the brown wire to the motor/module assembly.https://dl.dropboxusercontent.com/u/104923897/Power%20window%20VW%20Jul%206.pdf
No there is no computer system that could affect it. Did you verify you have a good ground?
Well if you sure you have power and ground at the motor then it should move with out having to unplug it.
There is a memory reset that requires access to a factory scan tool. See the link below.https://dl.dropboxusercontent.com/u/104923897/Memory%20eraseing%20Jul%206.pdf
