Abstract
A by-pass passage is provided around the blower of a vehicle ventilation and/or air conditioning system in order to avoid the flow resistance caused by the blower when it is not energized and accordingly increase the amount of air which may be rammed into the passenger cabin at low vehicle speeds. The passage is controlled by a door which is opened when the blower is off and the system is conditioned to induct fresh air from outside the vehicle.
