PROBLEM TO BE SOLVED: To prevent a door window from becoming uncontrollable as it is closed because switching contacts have become conductive owing to sprinkled water or condensation water. SOLUTION: This controller is provided with a relay for the down-motion supplying a battery voltage to a power window motor 5 as an actuating voltage and a down-side switch 6 supplying an exciting voltage to a relay 12 for the down-motion when the switch contact 6a is closed. And further, it is provided with a relay 13 for the up-motion supplying an actuating voltage to the power window motor 5 and an up-side switch 7 supplying an exciting voltage to the relay 13 for the up-motion when the switch contact 7a is closed and also provided with a contact 18 detecting water contents ahead of time when respective switch contacts 6a, 7a become conductive owing to water such as condensation water and a switching transister 20 supplying the battery voltage to the relay 12 for the down-motion as the exciting voltage, and a down-motion controller 19 turning on the transister 20 when the contact 18 detecting water contents has become conductive. |
