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.
