Abstract: A motor control arrangement includes a device connected to positive power such that device drives motor upon connecting to negative power. A switch connects to positive power upon actuation. A first transistor connects to switch via controller and connects between device and negative power. First transistor turns on causing device to connect to negative power upon switch actuation while controller is operational. A second transistor connects to switch and connects between device and negative power when controller is malfunctioned. Second transistor turns on causing device to connect to negative power upon switch actuation while controller is malfunctioned. A sensor connects to negative power upon contact with water. A third transistor connects to switch and sensor such that its collector-emitter path is connected in parallel to device.

Abstract: An electrical circuit arrangement for controlling a unit, such as an adjustment system for windows or a sliding sunroof, that is driven by a motor and is situated in a motor vehicle. The arrangement guarantees that, in the case of a short-circuit of circuit components, especially a control device operation of a motor is still possible, especially in a preferred direction of motor rotation, whereby the direction of rotation results in an opening of the unit and the short-circuit is caused by salt water for instance. Two circuit-breaker elements that operate the motor in either direction can be directly activated by an allocated circuit device which bypasses a failed control device. The remaining circuit-breaker element is blocked at least when the first circuit-breaker element is activated.
