Abstract: A motor vehicle door has a removable door outer skin, a module carrier, a door inner skin and a door inner trim. The door inner skin is connected on one side to the removable door outer skin and on the other side to the module carrier. A door inner trim is fixed on a side of the module carrier facing a vehicle interior and at least one guide rail of a cable window lifter is prefitted on the other side of the module carrier. In one of an upper and lower region of the guide rail, a pivotal bearing is provided with a pivotal axis running substantially horizontal and parallel to the door plane for the purpose of prefitting the guide rail on the module carrier. Proximate to the other of the upper and lower regions of the guide rail, a stop face is provided that is associated with a side of the door inner skin which faces the door outer skin.
