A method of making a door trim panel assembly for attachment to an inner panel of an automotive vehicle includes the steps of placing a door trim substrate into a cavity of a mold and placing at least one component into the cavity against the door trim substrate. The method also includes as an alternative of pre-joining the at least one component to the door trim substrate. The method also includes the steps of filling the cavity with a plastic material. The method further includes the steps of introducing steam into the mold to expand the plastic material to form a carrier and bond the carrier against the at least one component and door trim substrate to form a single door trim panel assembly.
