CAUTION
The Air Bag system must be disabled before the steering wheel and ignition switch are removed. Failure to disable the system may result in system repairs and possible personal injury. Do not damage, cut, or attempt to alter the yellow Air Bag wiring harness.

  1. Turn the steering wheel so that the vehicle's front wheels are pointing straight ahead.
  2.  
  3. Turn the ignition switch to the LOCK position. Remove the key.
  4.  
  5. Disconnect the negative and positive battery cables.
  6.  
  7. If equipped, properly disarm the Air Bag system.
  8.  
  9. Remove the steering wheel.
  10.  
  11. Remove the lower dashboard cover and disconnect the dimmer switch.
  12.  
  13. Remove the upper and lower steering column covers. Be careful with the wiring harness that runs through the lower cover; it may contain the Air Bag wiring.
  14.  
  15. Unscrew and remove the combination switch and Air Bag cable reel assembly, if equipped. The switch and cable reel assembly cannot be disassembled.
  16.  
  17. If equipped with an automatic transmission, disconnect the shift lock cable from the ignition lock cylinder.
  18.  
  19. Unscrew the switch from the ignition lock body and disconnect the harness from the fuse box.

  19. Turn the ignition to the ON position, but don't start the engine. If equipped, the AIR BAG warning light should turn on and flash on and off for seven seconds, and then turn off. This indicator light sequence indicates that the Air Bag system is functioning normally. If the AIR BAG light doesn't come on, or stays on longer than seven seconds, the system must be diagnosed.

For anti-theft reasons, the ignition switch is located on top of the steering column assembly and is completely inaccessible without first lowering the steering column. The switch is actuated by a rod and rack assembly. A gear on the end of the lock cylinder engages the toothed upper end of the actuator rod.

  1. Disconnect the negative battery cable.
  2.  
  3. Properly disarm the Air Bag system.
  4.  
  5. Remove the lower column trim panel, then remove the steering column-to-instrument panel fasteners and carefully lower the column for access to the switch.
  6.  
  7. Place the ignition switch in the OFF-LOCK position.
  8.  

If the lock cylinder was removed on vehicles through 1991, the actuating rod should be pulled up until it stops, then moved down one detent; the switch is now in the Lock position.

  1. Remove the ignition switch-to-steering column retainers, then remove the assembly.
  2.  

To install:
  1. Before installing the ignition switch, place it in the OFF-LOCK position, then make sure that the lock cylinder and actuating rod are in the Locked position (1st detent from the top or 1st detent to the right of far left detent travel).
  2.  

Most replacement switches are pinned in the OFF-LOCK position for installation purposes. If so, the pin MUST be removed after installation or damage may occur.

  1. Install the activating rod into the ignition switch and assemble the switch onto the steering column. Once the switch is properly positioned, tighten the ignition switch-to-steering column retainers to 35 inch lbs. (4.0 Nm).
  2.  

When installing the ignition switch, use only the specified screws since over length screws could impair the collapsibility of the column.

  1. Raise the column into position and secure, then install any necessary trim plates.
  2.  
  3. Properly arm the Air Bag system.
  4.  
  5. Make sure the ignition is OFF , then connect the negative battery cable.
