My 328 has small access plugs near the door handles which cover what appears to be openings for an emergency window crank. Removing a plug reveals a 7mm square shaft housed in a boss with an internal 18x1.5 mm thread. This shaft appears to be driven by a worm gear. It seems that any attempt to turn this shaft would damage something. What did Ferrari have in mind here? Has anyone seen a crank or tool intended for window operation?
