Abstract: A housing (30) to be mounted on a motor vehicle door (4) is disclosed. The housing includes a first air inlet (35) for admitting a first air stream (FR) into the housing (30), an air outlet (36), a chamber (37), delimited by at least one partition (38), arranged inside the housing (30), a second air inlet (39) for directly admitting a second air stream (FE) into the chamber (37), the first air inlet (35), the chamber (37) and the air outlet (36) being fluidically connected. According to the invention, the housing (30) comprises at least one movable flap (64, 74, 78). Also disclosed is an assembly of a door (4), comprising a housing support (61), and of such a housing (30).

Abstract: A motor vehicle heating, ventilating and/or air conditioning installation has air distribution, air mass flow and air temperature functions, each of which is adjustable between several different states. Control of these functions is exercised, by a control device which includes an electronic control module, in response to operation of a single manual control knob by the driver. The control knob acts on the control module when put into a position selected among several positions, each corresponding to one of the functions of the installation. The control member is displaced by tilting within its selected position, so as to act on the control member in such a way as to modify the state of the selected function.
