the actuator inside the sterring column that the lock cylinder turns is boken, this is a very complex job and is not for the home tech without a factory service manual.

Removal & Installation

1. Disconnect the negative battery cable. Remove the upper steering column shroud by removing the self-tapping screws.
   
2. Unfasten the four bolts retaining the lower steering column shroud, then remove the shroud.
   
3. Remove the lock screw, and detach the ignition switch electrical connector.
   
4. Rotate the ignition switch lock cylinder to the RUN position.
   
5. Remove the two screws retaining the ignition switch, and disengage the ignition switch from the actuator.
   

To install:

NOTE A new replacement switch will be set in the RUN position as received.

1. Adjust the ignition switch by sliding the carrier to the ignition switch run position.
   
2. Check to make sure the ignition switch lock cylinder is in the RUN position. The RUN position is achieved by rotating the ignition switch lock approximately 90 degrees from the LOCK position.
   
3. Install the ignition switch assembly into the column actuator hole. It may be necessary to move the ignition switch slightly back and forth to align the ignition switch mounting holes with the lock cylinder housing threaded holes.
   
4. Install the retaining screws and tighten to 53–71 inch lbs. (6–8 Nm).
   
5. Attach the electrical connector to the ignition switch. Tighten the lock screw to 7–11.5 inch lbs. (0.8–1.3 Nm).
   
6. Connect the negative battery cable. Check the ignition switch for proper function, including the START and ACC positions. Also, make sure the column is in the LOCK position.
   
7. Install the upper and lower steering column steering shrouds.
