A windshield washer control system for a vehicle having an air pressure source includes an electrically actuated control valve for controlling communication between the air pressure source and a bladder pump which squirts windshield washer fluid up to the windshield of the vehicle. A fluid restricting orifice is opened and closed by a solenoid actuator such that the pressure communicated to the bladder pump is limited to be below that of the air pressure reservoir. A second orifice controls communication from the pump to ambient atmosphere.
