A vehicle vent (12) for exhausting air from a vehicle occupant compartment includes a float valve (32) that prevents water that enters an outlet (24) of the vent from passing into the vehicle through the vent inlet (20) but which has a drain passage (36) for permitting a limited flow of the water to a drain (38) on the vent inlet side of the float valve (32). The vent (12) preferably includes a fan (40) that is most preferably energized by a solar panel (48). Mounting of the vent (12) can be provided on the vehicle roof, on the roof just forward of a vehicle back window, or as part of a sunroof.
