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.
