Door module and procedure for installing this module

The present invention refers to a door module (3) and to procedures for installing such a door module based on the use of different technical solutions for the fastening means both of the module (3) and of the window regulator guides (2), so that the installation of the module is possible without visual access, primarily at the lower part of the module. The means employed to achieve an efficient installation in terms of installation time and ease of handling are based on the use of spacers (3.3) separate from the fastening means (3.6,3.7), with a special design, which establish a distance between the window regulator guides (2) and the door module (3) during installation.
