A wiper system for automotive vehicles has a wiper receiving cavity between a windshield and an engine hood. The wiper receiving cavity has an opening through which a wiper goes in and out and which is open and closed by means of a lid member. The usual operation of the wiper system is performed in response to turning ON of a manually operable wiper switch. The wiper system has also another manual switch, operable independently of operation of the wiper switch, for allowing the lid member to be open in response to turning ON thereof. In addition, the wiper system includes means for changing a lower angular position thereof to a higher position.
