Sluggish window operation (or is it a new motor needed? or one side one has to have a helping hand up & it never seals itself?) In terms of sluggish - it could be the motor, but the power going to the motor is controlled by a chip in the window control box in the boot. If
omeone;s updated the door seals to the newer ones and not re-chipped the control box, you will definitely need the newer chips.

Can anyone shed any light on the control box chips - how to identify and/or replace them?
