A vehicle ventilation assembly comprising; a plenum chamber (21, figure 4) with an inlet 7, and an outlet 13 displaced laterally to each other. The ventilation assembly may have the inlet exposed to the exterior of the vehicle and the outlet exposed to the interior of the vehicle, and may be placed at the foot of a windscreen (1, figure 1). The assembly may have two outlets, with the inlet located in-between, so that fresh air from the exterior of the vehicle may flow freely through the assembly to reach the interior of the vehicle, but a good proportion of any water, dust, and the like entering the inlet will strike an internal wall of the plenum chamber rather than pass through the outlet, figure 4. Water entering in this way can be allowed to exit via a water drain aperture in a lower portion of the plenum chamber, which can preferably drain to the exterior of the vehicle. The inlet may be covered by a grill and have the drive spindle of a windscreen wiper extend through, figure 5.
