Abstract: A window regulator system for a window coupled to a door and movable between fully open and closed positions and a short drop position and method of operation are disclosed. The system includes rails with window regulator lifter plate assemblies being moveable along the rails by cables. A motor winds the cables to move the window. An electronic control unit detects operation of at least one of a door handle and a latch of the door to identify a short drop request corresponding to the door shut or opened. The electronic control unit ensures that no freeplay exists in the window regulator system to provide accurate movement of the window and controls the motor to selectively raise the window to the fully closed position in response to the door being shut and temporarily lower the window to the short drop position in response to identifying the short drop request.
