Window deflector or weather shield is mounted above the doors of some car, to protect the inside of the car from rain or other precipitation in case of slightly opened windows. Additionally, it may help to prevent precipitation entering the interior in case of an opened door, e.g. dropping from the roof or directly from the air.
