An actuating drive for an air passage apparatus for engine cooling in a vehicle is provided. The actuating drive comprises a drive motor for adjusting the air passage apparatus and a control unit for controlling the drive motor, in which control unit are stored operating parameters for a first operating mode of the drive motor, in order to adjust the air passage apparatus between the open and closed position, as intended. The actuating drive has a drive element which is drivable by the drive motor and a driven element movable along an adjustment path with the drive element for adjusting the air passage apparatus. The drive element and the driven element are coupled together in an operating state for adjusting the air passage apparatus, and are decoupled from each other in another operating state, whereby the driven element is movable with respect to the drive element. |
