A controller system is provided for a motorized moveable striker assembly on a vehicle door or window. The assembly includes a striker on the door post which is moveable by an electric motor between extended and retracted positions. A latch on the door releasably engages the striker. Switches in the latch sends signals to the controller to actuate the motor. After the latch is engaged, the controller retracts the striker from the extended position to fully close the door.
