ABSTRACT:
A device is described for controlling the operation of an electric motor for driving the arm of a windshield wiper of an opening window, particularly the rear window of an automotive vehicle. The device has a control unit for supplying power to the motor. The operation of the motor is controlled by a key contact of the vehicle and a control element. The key contact and the control element are under user control and are connected in series between a power supply source, the control unit, and a contact for detecting the opening or closing of the window. The device is further characterized in that the open window detection contact is connected to a control unit data input so that it controls restarting the motor only after opening and closing of window and only after reinitialization of the control element by interruption of the control element and by a new user action on the control element.
