Removal
To remove adjuster control knob, use body spoon
and locking type pliers as shown in Figure 20.
lnstallation
1. Make
pencil mark on seat adjuster control arm 25
mm
(1 ") from end of arm as a guide for full depth
fit.
2. Secure locking type pliers
to control arm below
pencil line.
3. Insert knob on arm and press firmly while
holding restraint with locking type pliers. If
necessary, use rubber mallet.
4. Gate marks on knob should face down on bucket
seats and to the rear on regular seats. Care should

FRONT SEAT ASSEMBLY - MANUAL AND
POWER SEATS
Seat assemblies are secured to the floor pan by
nuts installed on floor pan anchor plate studs.
The manually operated front seat assemblies have
manual seat adjusters to provide fore and aft movement
of the seat. When the control lever located at the front
of the seat is actuated to the left, the seat adjusters
unlock, permitting horizontal travel of the seat. When
the seat is in the desired position and the locking lever
is released, the seat is locked.
The power six-way seat adjusters are actuated by
three
12V, reversible, permanent magnet motors with
a built-in circuit breaker. The motors are energized by
a toggle-type control switch bolted on the seat side
panel (Fig. 2
1).
The three motors respectively direct drive the
front and rear vertical
gearnuts and a horizontal
actuator. When the adjusters reach the limit of travel,
their torque is absorbed through the rubber mounted
grommets between the motor and the support. An
overload relay is provided in the circuit should
excessive stall torque be applied to the motor.
Front seats are secured to the floor pan by nuts
installed into weld studs on floor pan anchor plates.
Removal and lnstallation
1. Operate seat to full-forward position. If six-way
power seat
is operable, operate seat to
full-forward and up positions. Where necessary to
gain access to adjuster-to-floor pan attaching
nuts, remove adjuster rear foot covers and/or
carpet retainers.
2. Remove track covers where necessary; then
remove adjuster-to-floor pan rear attaching nuts.
Operate seat to full-rearward position. Remove
adjuster front foot covers; then remove
adjuster-to-floor pan front attaching nuts.
On seats with power adjusters, tilt seat rearward
and disconnect feed wire connector.
3. Remove seat assembly from car.
4. Prior to installing seat assembly, check that both
seat adjusters are parallel and in phase with each
other. In the event the adjusters are out of phase
(one adjuster reaches its maximum horizontal or
vertical travel in a given direction before the other
adjuster), phase adjusters as described in step
5c
under Front Seat Adjuster Assembly - Removal
and Installation.
5. To install seat assembly, reverse removal
procedure.
6. Tighten seat adjuster-to-floor pan attaching bolts
or nuts 20 to 28
N.m (15 to 21 ft-lb). Check
operation of seat assembly to full limits of travel.
FRONT SEAT ADJUSTER ASSEMBLY -
MANUAL AND POWER
Removal and lnstallation
1. Remove front seat assembly with adjusters
attached and place upside down on a clean,
protected surface.
2. On manual seat adjusters, remove seat adjuster
assist spring from adjuster being removed. If
removing right adjuster, squeeze
hooked end of
seat adjuster locking wire together and slide
retaining spring over hump in locking wire and
remove locking wire from adjuster.
3. On power-operated seats, disconnect drive cables
at adjuster being removed by squeezing oblong
connector to detach.
4. Remove adjuster-to-seat bottom frame front and
rear attaching bolts or nuts and remove seat
adjuster from seat (Fig. 22). On some seats,
spacers are installed between the seat adjusters
and seat frame or seat adjuster and floor pan.
Note location of spacers for reinstallation in same
position(s).
5. To install, reverse removal procedure.
NOTICE: See NOTICE on page 9H-1 of this
section.
a. If a manual adjuster is being replaced,
install new adjuster control knob as
described under Manual Seat Adjuster
Control Arm Knob.
