Common fault on these I'm afraid - from R reg onward.
They never resolved it - you will need to have the electronic/electrical parts replaced - best bet is to find one in a scrapyard because they cost a fotrune from the main dealer.
You will then have to disassemble the door lining and replace the control units. Word of warning - I am not sure as to the location on this model (2002 model) - it is not uncommon for the control units to be placed in different areas of the car - you may find the unit for the driver door is situated under a panel/in a panel or behind the nearside passenger door.
You will need to know the location of the control unit before attempting this - word of advice - if you get one from a scrapyard try to obtain the auto window unit as well (if fitted) as these are also a common fault
