Abstract
A power window apparatus for a vehicle, which can open or close a door window by manual operation of a power window switch for energizing either of window-opening and closing relays for rotating a motor in the forward or reverse direction or by automatic operation of the same switch to cause an auto-latching circuit or a control unit to maintain either of the relays in an energized state until the window becomes fully opened or closed. The apparatus is provided with a switch for deenergizing a coil of the window-closing relay by disconnecting the control circuit for latching the energized window-closing relay, thus enabling the opening of the window by manual switch operation whenever an abnormal operation of the auto-latch control system occurs with simultaneous energization of both the window-opening and closing relays in an accident such as the vehicle sinking into water.
