IGNITION SWITCH
WARNING
- Before attempting any repairs involving the steering wheel or
disassembly of it, ensure that the Supple mental Inflatable Restraint (Air Bag)
system is properly disarmed.
REPLACEMENT
Fig. 1: Ignition switch
The switch is located inside the channe l section of the brake pedal support and
is completely inaccessible without firs t 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 rod.
1. Lower the steering column; be sure to properly support it.
2. Put the switch in the Off-Unlocked position. The Off-Unlocked position is
two detents from the top.
3. Remove the two switch screws and remove the switch assembly.
To install: 4. Before installing, place the new switch in the Off-Unlocked position.
Make sure the lock cylinder and actuating rod are in the Off-Unlocked
(second detent from th e top) position.
5. Install the activating rod into the switch and assemble the switch on the
column. Tighten the mount ing screws. Use only the specified screws
since overlength screws could impair the collapsibility of the column.
6. Reinstall the steering column.

1. Properly disable the SIR
air bag system, if equipped.
2. Place the lock in the Run position.
3. Remove the lock plate, turn signal switch and buzzer switch.
4. Remove the screw and lock cylinder.
CAUTION - If the screw is dropped on removal, it could fall into the column,
requiring complete disassembly to retrieve the screw.
To install:
5. Rotate the cylinder clockwise to a lign cylinder key with the keyway in the
housing.
6. Push the lock all the way in.
7. Install the screw. Tighten the screw to 14 inch lbs. (1.5 Nm) for
adjustable columns and 25 inch lbs. (2.8 Nm) for standard columns. Re-
center the SIR coil assembly as previously directed.
STEERING COLUMN
WARNING - Before attempting any repairs involving the steering wheel or
disassembly of it, ensure that the Supple mental Inflatable Restraint (Air Bag)
system is properly disarmed.
REMOVAL & INSTALLATION
The front of the dash mount ing plates must be loosened whenever the steering
column is to be lowered from the instrument panel.
1. Disconnect the negative battery cable.
2. On 1990-92 vehicles, disable the S upplemental Inflatable Restraint (SIR)
system as follows: a. Turn the steering wheel so th e vehicle's wheels are pointing
straight-ahead.
The wheels of the vehicle must be in the straight-ahead position
and the steering column in the locked position before proceeding
with steering column remo val. Failure to follow this procedure will
cause the SIR coil to become uncentered, resulting in damage to
the coil assembly.
b. Remove the SIR fuse from the fuse block.
c. Remove the left sound insulator by removing the nut from the stud
and gently prying the insulator from the knee bolster.
d. Disconnect the Connector Position Assurance (CPA) and yellow 2-way SIR harness connector at the base of the steering column.
3. Remove the nut and bolt from t he upper intermediate shaft coupling.
Separate the coupling from the lo wer end of the steering column.
4. Remove the steering w heel, if the column is to be replaced or repaired
on the bench.
5. Remove the knee bolster and bracket, if equipped.

6. Remove the bolts attaching the toe plate to the cowl.
7. Disconnect the electrical connectors.
8. Remove the capsule nuts attachi
ng the steering column support bracket
to the instrument panel.
9. Disconnect the park lock cable from the ignition switch inhibitor, if
equipped with automatic transmission.
10. Remove the steering column from the vehicle.
To install:
If a replacement steering column is bein g installed, do not remove the anti-
rotation pin until after the steering co lumn has been connected to the steering
gear. Removing the anti-rotation pin before the steering column is connected to
the steering gear may dam age the SIR coil assembly.
11. Position the steering column in the vehicle.
12. Connect the park lock cable to the ig nition switch inhibitor on vehicles
with automatic transmission.
13. Install the capsule nuts attaching the steering column support bracket to
the instrument panel and tighten to 20 ft. lbs. (27 Nm).
14. Install the nut and bolt to the upper intermediate shaft coupling attaching
the upper intermediate shaft to the steer ing column. Tighten the nut to 44
ft. lbs. (60 Nm).
15. Install the bolts attaching the toe pl ate to the cowl and tighten to 58 inch
lbs. (6.5 Nm).
16. Connect the electrical connectors.
17. Remove the anti-rotation pin if a se rvice replacement steering column is
being installed.
18. Install the knee bolster and bracket, if equipped.
19. Install the sound insulator panel.
If SIR coil has become uncentered by turni ng of the steering wheel without the
column connected to the st eering gear, follow the proper adjustment procedure
for the SIR coil assembly before proceeding.
20. Install the steering wheel.
21. Connect the negative battery cable.
22. Enable the SIR system as follows: a. Connect the yellow 2-way SIR harness connector to the base of
the steering column and CPA clip and install the SIR fuse.
b. Install the left sound insulator.
c. Turn the ignition switch to the RUN position and verify that the
inflatable restraint indicator fl ashes 7-9 times and then turns OFF.
If the indicator does not respond as stated, a problem within the
SIR system is indicated.

6. Refill the pump with fluid and
bleed by turning the pulley
counterclockwise (viewed from the front). Stop the bleeding when air
bubbles no longer appear.
7. Install the pump belt on the pulley and adjust the tension.
SYSTEM BLEEDING 1. Fill the reservoir with power steering fluid.
The use of automatic transmission flui d in the power steering system is NOT
recommended.
2. Allow the reservoir and fluid to sit undisturbed for a few minutes.
3. Start the engine, allow it to run for a mome nt, then turn it off.
4. Check the reservoir fluid level and add fluid if necessary.
5. Repeat the above steps until the fluid level stabilizes.
6. Raise the front of the vehicle so that the wheels are off of the ground.
7. Start the engine and increase t he engine speed to about 1500 rpm.
8. Turn the front wheels right to le ft (and back) several times, lightly
contacting the wheel stops at the ends of travel.
9. Check the reservoir fluid level. Add fluid as required.
10. Repeat step 8 until the fluid leve l in the reservoir stabilizes.
11. Lower the vehicle and repeat steps 8 and 9.
