Claim:
Pre-assembly unit for a motor vehicle and for connection with a door frame of the motor vehicle, the pre-assembly unit comprising: a window frame comprising first cutouts, the window frame being separate from but connectable with the door frame; an equipment carrier that is connected to but disconnectable from the window frame via first quick-release fasteners engaged within the first cutouts of the window frame and the equipment carrier being connectable to the door frame via second quick-release fasteners engagable within second cutouts of the door frame, the equipment carrier having a wet side (N) and a dry side (T) for dividing the door frame into a wet area and a dry area; a side window guided at least within the window frame; a window lifting mechanism, which is connected to the side window in order to raise or lower the side window, the window lifting mechanism comprising attachment legs and rolls; at least one fixing means for joining the window lifting mechanism to the equipment carrier, said fixing means adapted to be undone from the dry side of the equipment carrier, the fixing means comprising third quick-release fasteners coupling the equipment carrier to attachment legs of the window lifting mechanism; and wherein the window lifting mechanism is attachable to the door frame from the dry side of the equipment carrier, at least one of the second quick release fasteners is removable from the equipment carrier to expose an aperture that provides access to the window lifting mechanism such that the window lifting mechanism is attachable to the door frame via screws mating with hollow rotary axes of the rolls of the window lifting mechanism wherein the window lifting mechanism is independently connectable to the door frame such that upon removing the equipment carrier from the door frame, the window lifting mechanism can remain connected to the door frame.
