Have you studied the Bentley diagram for the power windows?  Not
trivial.  As I recall a fault in one switch can make the window in the
other door inoperative.  Switches can be replaced with ones from a
Jetta.  You have to solder the wires on.  Don't let them project too
far into the door: the window will hit them.   :-(
