Lincoln F4DZ-11572-B Ignition Switch Assembly

As a process of replacement of the ignition switch, the user is advised to pull the cable off the negative terminal of the battery. Next, take out the centre trim panel and the driver's side knee bolster and the next are the steering column covers, and the tilt-column handle if any. Rotate the ignition key to the Run position and disconnect the electrical connector to the ignition switch and then remove the retaining screws. Remove the ignition switch from the actuator pin by pulling out the mentioned part of the switch from the car. Check that the actuator pin slot in the new ignition switch is located in the Run position, insert the new ignition switch on the actuator pin and tighten the retaining screws and using space provided, calibrate the screws for the alignment of the screw holes. That completes the removal of the cruise control but do the reverse in order to finish the installation and test the unit function in the lock, start and accessory positions. For the Ignition Lock Cylinder as well this requires disconnecting the cable from the negative terminal, rotating the key to the run position and driving a 1/8-inch punch into the hole at the bottom of the steering column cover surround the Ignition Lock Cylinder. Pull out on the Ignition Lock Cylinder while depressing the punch to eject it. To remove the cylinder for replacement, push on the pin near the last of the cylinder and turning a quarter counterclockwise from the Stop position to the Run position and the cylinder falls out of the interlocking washer which must be seated firmly. Finally, using the position of the key that is labelled 'Off', re-align it back to this state to enable proper positioning of the retaining pin into the situated locating hole; the same key should now be turned to confirm a proper working lock in all the respective created positions, finally, reinstalling the lock using the reverse procedure highlighted above.

Turn the lock key to the Run position.

Remove the metal reinforcement panel just behind the knee bolster for access to the switch. The ignition switches on these models are located to the right of the steering column and are accessible after the knee bolster reinforcement panel is removed.

An ohmmeter or self-powered test light is needed.

The remainder of the installation is the reverse of removal. Check for proper operation of the ignition switch in the lock, start, and accessory positions.

Disconnect the ignition switch electrical connector and remove the switch retaining screws (Unplug the electrical connector and remove the ignition switch retaining screws).

Align the switch pin with the slot in the lock/column assembly, ensuring both the switch and the ignition key are in the RUN position.

Disconnect the cable from the negative terminal of the battery.

Disconnect the negative cable from the battery, and if equipped with an airbag, disconnect the positive cable as well.

If the continuity isn't as specified, replace the switch.
