PROBLEM TO BE SOLVED: To lower a window glass when a fall switch is turned on even under the state, in which a circuit is moistened with water. SOLUTION: When water leaks in a circuit containing an automatic switch, etc., installed to a door electronic control unit (a door ECU) and a signal is input from the door ECU to transistors TR1, TR2, relay coils 21, 23 are excited, relay contacts are brought simultaneously to an on state, and a driving motor M is not driven. When specified on operation is conducted to a fall switch 28 at that time, a rise switch 29 is grounded. Accordingly, the driving motor M is turned forward, and a wire type or arm type regulator is driven by the driving motor M and a window glass is lowered. |
