04audi, window goes up by itself (when down) while driving or did you mean
that when you want the window to go up, that it only goes up sometimes
while using the switch?
The switch can be checked via a scan tool connected to the Comfort
Control Module. While operating the switch you can check to see if
the control module "sees" an open or close window signal from the switch.
If no signal is "seen" chances are that the switch is no good (could be
wiring too though).
Try opening / closing "all" windows with the key in the door handle
from the outside of the car. Hold the key in either the lock or unlock
position to activate ALL windows.
If the driver window still hangs-up (does not open or close with the
other windows), then I would think there is a problem with the window
regulator/module in that door.
