Ignition and Start Switch Replacement

Removal Procedure

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component.

Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable.

3. With a small flat-bladed tool remove the ignition switch trim ring from ignition switch.
4. Remove the accessory trim plate from the IP carrier.
5. Remove the upper steering column trim cover from the steering column.

    Carefully drill a pilot hole through the plastic housing with a 1/8 inch drill bit.

    11.4.

    Carefully drill a larger hole at the pilot location, and slightly into the ignition switch lock cylinder surface to break the release button retaining spring using a 9/32 inch drill bit.

    11.5.

    Remove portions of the broken spring from the hole using a small suitable tool.

    11.6.

    Grasp the ignition switch lock cylinder and remove it from the switch housing.

7. Install the ignition switch housing to the IP carrier.

   Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

8. Install the ignition switch bolts.

   Tighten

   Tighten the ignition switch bolts to 2 N·m (18 lb in).

9. Install the instrument panel cluster to the IP carrier.
10. Install the instrument panel cluster trim plate to the IP carrier.
11. Install the upper steering column trim cover to the steering column.
12. Install the accessory trim plate to the IP carrier.
13. Install the ignition switch trim ring to the ignition switch.
14. Enable the SIR system.
15. Connect the negative battery cable.
