Windshield Frame Lock Assembly
The windshield frame lock assembly consists of the top lock motor positioned in the center of the top frame and two lock drive mechanisms positioned on the left and right sides of the top frame. The operation of the lock motor and drive mechanisms is similar to the E36 fully automatic top system. The drive mechanisms have been redesigned for smoother operation, however they still are responsible for unlocking the top from the windshield and raising the front of the top past the tension point. Flexible drive shafts are used activate the lock assemblies and drive the tension linkage rods to raise the top past the tension position.

Two hall sensor switches located on the left lock drive assembly are used to detect the position of the top against the windshield frame.
