Ignition Switch
WARNING: This page is about a different car, the 2002 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
The ignition lock cylinder and switch are two components. When the lock cylinder ignition key is turned to different positions, it is aligning electrical contacts in the ignition switch. Electrical contacts are made in the ACC (Accessory), RUN and START positions. In the OFF position the switch is open and the key can be removed.
The ignition switch and lock cylinder assembly is mounted to the right of the steering column in the instrument panel. An opening in the instrument panel provides key access to the lock cylinder.
