ABSTRACT:
A synchronizing circuit for a combination window and door locking system for automotive vehicles. During normal operation the door's are locked and unlocked by continued rotation of the window lifter motor. If the door locks have been manually operated between motorized operations, the locked and unlocked positions of the door locks can become out of synchronization with one another. The synchronization circuit utilizes and interconnected series of switches, position-sensitive switches and relays to control the window lifter motors. During a locking operation, the circuit automatically sequences the lifter motors first through an unlocking operation and then into their door locking positions.
