PURPOSE:To save the power consumption of a vehicle by stopping the actuation of a rear hot wire device (so-called rear differential fogger) provided in the vehicle when the actuation of the rear hot wire device overlaps that of an air conditioning device. CONSTITUTION:The ever-closed contact 15a of a relay 15 is connected between the fuse 1 of a rear hot wire device and a differential fogger switch 2. The coil 15b of the relay 15 is connected in parallel with the coil 7b of an air conditioning relay 7 for an air conditioner circuit. When the switch 2 is turned on, current is applied to a rear hot wire 4 and the fogging of a rear window is removed. When an air conditioning switch 9 is turned on in this state, the coils 7b and 15b are energized and a contact 7a is closed and then the contact 15a is opened. As a result, current application to the rear hot wire 4 is disconnected and a cooling fan motor 13 is actuated. Thus, when the switch 9 is turned on while the rear hot wire device is being actuated, the air conditioning device is actuated and the removal of fogging is continued. On the other hand, since the rear hot wire device is stopped, waste battery consumption is eliminated. |
