Windshield Frame Lock Assembly
The windshield frame lock assembly consists of the top lock motor positioned in the cen-
ter 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 frame. One switch for the cowl lock signal and the second for the ten-
sion point position.
