(2) From the underside of the steering wheel,
remove the two screws that secure the driver airbag
to the steering wheel armature (Fig. 10).
(3) Pull the driver airbag away from the steering
wheel far enough to access the two wire harness con-
nectors at the back of the airbag.
(4) Disconnect the clockspring horn switch pigtail
wire connector from the horn switch feed pigtail wire
connector, which is located at the back of the driver
airbag.
CAUTION: Do not pull on the clockspring pigtail
wire to disengage the connector from the driver air-
bag inflator connector receptacle.
(5) The clockspring driver airbag pigtail wire con-
nector is a tight snap-fit into the airbag inflator con-
nector receptacle, which is located at the back of the
driver airbag. Firmly grasp and pull or gently pry on
the clockspring driver airbag wire harness connector
to disconnect it from the airbag inflator connector
receptacle.
(6) Remove the driver airbag from the steering
wheel.
(7) If the driver airbag has been deployed, the
clockspring and the steering column must be
replaced. (Refer to 8 - ELECTRICAL/RESTRAINTS/CLOCKSPRING - REMOVAL) (Refer to 19 - STEER-
ING/COLUMN - REMOVAL).
DISASSEMBLY
The horn switch is integral to the driver airbag
trim cover. If either component is faulty or damaged,
the entire driver airbag trim cover and horn switch
unit must be replaced.

INJURIES.
WARNING: USE EXTREME CARE TO PREVENT ANY
FOREIGN MATERIAL FROM ENTERING THE DRIVER
AIRBAG, OR BECOMING ENTRAPPED BETWEEN
THE DRIVER AIRBAG CUSHION AND THE DRIVER
AIRBAG TRIM COVER. FAILURE TO OBSERVE THIS
WARNING COULD RESULT IN OCCUPANT INJURIES
UPON AIRBAG DEPLOYMENT.

THIS WARNING COULD RESULT IN OCCUPANT
INJURIES UPON AIRBAG DEPLOYMENT.
(1) Carefully position the driver airbag in the trim
cover. Be certain that the horn switch feed and
ground pigtail wires are not pinched between the air-
bag housing and the trim cover locking blocks.
(2) Engage the upper and lower trim cover locking
blocks with the lip of the driver airbag housing, then
engage the locking blocks on each side of the trim
cover with the lip of the housing. Be certain that
each of the locking blocks is fully engaged on the lip
of the airbag housing (Fig. 14).(3) Reinstall the horn switch ground pigtail wire
eyelet terminal over the left upper airbag housing
stud.
(4) Reinstall the upper and lower airbag trim cover
retainers over the airbag housing studs. Be certain
that the tabs on the retainers are engaged in the
retainer slots of the trim cover locking blocks (Fig.
13).
(5) Install and tighten the nuts that secure the
trim cover retainers to the airbag housing studs.
Tighten the nuts to 10 N´m (90 in. lbs.).
(6) Route the horn switch feed pigtail wire
between the inflator housing and the right upper air-
bag housing stud.
(7) Reinstall the plastic wire retainer onto the
right upper airbag housing stud to capture horn
switch feed pigtail wire.
(8) Reinstall the driver airbag onto the steering
wheel. (Refer to 8 - ELECTRICAL/RESTRAINTS/
DRIVER AIRBAG - INSTALLATION).
INSTALLATION
The following procedure is for replacement of a
faulty or damaged driver airbag. If the driver airbag
has been deployed, the clockspring and the steering
column assembly must also be replaced. (Refer to 8 -

(1) Assemble the driver airbag trim cover onto the
airbag housing. (Refer to 8 - ELECTRICAL/RE-
STRAINTS/DRIVER AIRBAG - ASSEMBLY).
(2) When installing the driver airbag, reconnect
the clockspring driver airbag pigtail wire harness
connector to the airbag inflator connector receptacle
by pressing straight in on the connector (Fig. 10). You
can be certain that the connector is fully engaged by
listening carefully for a distinct, audible click as the
connector snaps into place.
(3) Reconnect the clockspring horn switch pigtail
wire harness connector to the horn switch feed pig-
tail wire connector, which is located on the back of
the driver airbag.
(4) Carefully position the driver airbag in the
steering wheel. Be certain that the clockspring pig-
tail wires in the steering wheel hub area are not
pinched between the driver airbag and the steering
wheel.(5) From the underside of the steering wheel,
install and tighten the two screws that secure the
driver airbag to the steering wheel armature.
Tighten the screws to 10.2 N´m (90 in. lbs.).
(6) Do not reconnect the battery negative cable at
this time. The airbag system verification test proce-
dure should be performed following service of any
airbag system component. (Refer to 8 - ELECTRI-
CAL/RESTRAINTS - STANDARD PROCEDURE -
