Ignition Switch: Service and Repair

Steering Lock Assemblies:

NOTE: THREE types of steering lock assemblies were used on this vehicle. One style uses a screw-on lock cylinder cap (VERSION 2), the other uses a plug-on type (VERSION 1). A new screw-on type (VERSION 3, similar to VERSION 2) is the only replacement part available. Some modification of the dash cut-out as well as a larger starter switch bezel may be required for installation. Component replacement for all three types is the same except where indicated in the text.

The steering lock assembly is comprised of three main components:

1. Ignition lock (locking cylinder)
2. Ignition switch (starter switch)
3. Steering column lock (steering lock)

Use this procedure to replace the IGNITION SWITCH. Additional information is also available for IGNITION LOCK replacement and STEERING COLUMN LOCK replacement.
