16. Remove the steering column assembly (6) from
the vehicle.
17. Disassemble or transfer any components to be
replaced.
INSTALLATION
WARNING: Before servicing the steering column the airbag system must be disarmed. Refer to electrical
restraint system for service procedures. Failure to do so may result in accidental deployment of the airbag
and possible personal injury.
CAUTION: All fasteners must be torqued to specification to ensure proper operation of the steering column.
1. Position the steering column on the dash panel
support and loosely install the mounting nuts (1&3).
2. Firmly slide the steering column upward against the
studs in dash panel and hand tighten the nuts.
3. Install the steering shaft coupler (5) on the steering
shaft and loosely install anewbolt (4).
4. Center steering column in dash opening and
tighten mounting nuts (1&3) to 28 Nꞏm (250 in.
lbs.).
NOTE: Torque the upper left nut first then the
lower right nut. Then torque the lower left nut then
the upper right nut.
NOTE: A new bolt must be used for reinstallation.
5. Tighten the coupler bolt (4) to 57 Nꞏm (42 ft. lbs.).
6. Install a new brake light switch (2) (Refer to 8 -
ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/BRAKE LAMP SWITCH - REMOVAL).
Page 2418 of 5267
7. Install the shifter cable (5). (Refer to 21 - TRANS-
MISSION/TRANSAXLE/AUTOMATIC - 32RH/GEAR
SHIFT CABLE - INSTALLATION)
8. Connect the wiring harness (8) to the column.
9. Install the clockspring (Refer to 8 - ELECTRICAL/
RESTRAINTS/CLOCKSPRING - REMOVAL).
10. Install the shrouds (1&2).
11. Align the spline on the wheel hub to shaft.
12. Then install the steering wheel and install anewbolt. Tighten the bolt to 61 Nꞏm (45 ft. lbs.).
13. Install the airbag (Refer to 8 - ELECTRICAL/RESTRAINTS/DRIVER AIRBAG- INSTALLATION).
14. Install the tilt lever knob (2).
Page 2419 of 5267
15. Install the steering column opening cover (1) and
kneeblocker (2) (Refer to 23 - BODY/INSTRU-
MENT PANEL/STEERING COLUMN OPENING
COVER - INSTALLATION).
16. Install the negative battery terminal.
17. Test the operation of the horn, Electronic PRNDL
Indicator, lights and any other functions that are
steering column operated.

IGNITION SWITCH
DESCRIPTION
The ignition switch (1) is located on the steering col-
umn. It is used as the main on/off switching device for
most electrical components. The mechanical key cylin-
der is used to engage/disengage the electrical ignition
switch.
OPERATION
Vehicles equipped with an automatic transmission and a steering column mounted shifter:an interlock
device is located within the shift cable. This interlock device is used to lock the transmission shifter in the PARK
position when the key cylinder is in any position and the brake pedal is not depressed.
DIAGNOSIS AND TESTING
IGNITION SWITCH
TEST AND REPAIR
If the key removal effort is excessive on a vehicle with
a automatic transmission first adjust the shift linkage
(5), (Refer to 21 - TRANSMISSION/TRANSAXLE/AU-
TOMATIC - 46RE/GEAR SHIFT CABLE - ADJUST-
MENTS).
If the ignition switch (1) effort is excessive remove the
ignition key cylinder (3) from the steering column.
(Refer to 19 - STEERING/COLUMN/LOCK CYLINDER
HOUSING - REMOVAL). Check the turning effort of
the key cylinder. If the ignition key cylinder effort is
excessive replace the key cylinder (3).

REMOVAL
SERVICE PRECAUTIONS
NOTE: The steering column on vehicles equipped with an automatic transmission is not equipped with an
internal locking shaft with the ignition cylinder. Alternative methods of locking the steering wheel for ser-
vice will have to be used.
To service the steering wheel, switches or airbag, Refer to Electrical Restraints and follow all WARNINGS and CAU-
TIONS.
WARNING: The airbag system is a sensitive, complex electro-mechanical unit. Before attempting to diag-
nose, remove or install the airbag system components you must first disconnect and isolate the battery
negative (ground) cable. Then wait two minutes for the system capacitor todischarge. Failure to do so
could result in accidental deployment of the airbag and possible personalinjury. The fasteners, screws, and
bolts, originally used for the airbag components, have special coatings and are specifically designed for the
airbag system. They must never be replaced with any substitutes. Anytime anew fastener is needed,
replace with the correct fasteners provided in the service package or fasteners listed in the parts books.
CAUTION: Do not hammer on steering column shaft. This may cause damage to the shaft or bearing.
CAUTION: Do not attempt to remove the pivot bolts to disassemble the tilting mechanism.
The ignition key must be in the key cylinder for cylinder removal. The key cylinder must be removed first before
removing ignition switch.
1. Remove the negative (ground) cable from the battery.
2. Disable the airbag, (Refer to 8 - ELECTRICAL/RESTRAINTS/DRIVER AIRBAG- REMOVAL).
3. Remove the kneeblocker and steering column reinforcement panel.
4. Remove the lower and upper shrouds.
5. Remove key cylinder. (Refer to 19 - STEERING/COLUMN/LOCK CYLINDER HOUSING - REMOVAL).
6. Remove the tilt lever release knob bracket. (if
equipped).

7. Disconnect the electrical connector at rear of igni-
tion switch (4).
8. Remove ignition switch mounting screws (2).
9. Using a small screwdriver, push on locking tab (3)
and remove switch (1) from steering column.
INSTALLATION
The ignition key must be in the key cylinder for cylinder installation. Thekey cylinder must be removed first before
installing ignition switch.
1. Before installing ignitionswitch (1), rotate the slot
in the switch to the ON position.
2. Position switch (1) to column and install the mount-
ing screws (2). Tighten screw to 3 Nꞏm (26 in. lbs.).
3. Connect the electrical connector to rear of the igni-
tion switch (4). Make sure that locking tabs are fully
seated into wiring connector.
