Abstract: A door module of a vehicle door includes a carrier plate having a cable window regulator with at least one guide rail, and a door structure which is or can be joined to the carrier plate. A cable deflection region of the guide rail extends beyond an outer edge of the carrier plate. The cable deflection region is provided with a joining contour which, when joined, is form-lockingly inserted in a receiving contour of the door structure. The joining contour engages behind the receiving contour in such a way that the cable deflection region is stabilizingly held in a direction perpendicular to the cable deflection region. A vehicle door having the door module is also provided.
