CLUTCH DISC REPLACEMENT
REMOVAL
(1) Remove transaxle. See Group 21, Manual Tran-
saxle, for procedure. (2) Mark clutch cover and flywheel, to maintain
their same relative positions when installing clutch
assembly (Fig. 4). (3) Insert Clutch Disc Aligning Tool C-4676
through the clutch disc hub to prevent the clutch disc
from falling and damaging the facings (Fig. 5). (4) Loosen clutch cover attaching bolts, one or two
turns at a time, in a crisscross pattern, to release
spring pressure evenly and avoid cover damage.
CAUTION: Do not touch the clutch disc facing with
oily or dirty hands. Oil or dirt transferred from your
hands onto the clutch disc facing may cause clutch
chatter.
(5) Remove the clutch pressure plate and cover as-
sembly and disc from flywheel. Handle carefully to
avoid contaminating the friction surfaces.
INSPECTION
(1) Inspect for oil leakage through engine rear
main bearing oil seal and transaxle input shaft seal.
If leakage is noted, it should be corrected at this
time. (2) The friction faces of the flywheel and pressure
plate should not have excessive discoloration, burned
areas, small cracks, deep grooves, or ridges. Replace
parts as required.
CAUTION: Do not polish flywheel to a ``mirror like''
surface.

GENERAL INFORMATION
Power seats can be adjusted in six different direc-
tions up, down, forward, back, tilt forward, or tilt
rearward. A three armature permanent magnet reversible mo-
tor is coupled through cables to worm gear box assem-
blies located in the seat tracks, providing the various
seat movements. The electrical circuit is protected by a 30 amp circuit
breaker located on the fuse block.
TEST PROCEDURES
Before any testing is attempted the battery should be
carefully charged and all connections and terminals
cleaned and tightened to insure proper continuity and
grounds. With dome lamp on, apply switch in direction of
failure. If dome lamp dims the seat motor is trying to
work indicating mechanical jamming. If dome lamp
does not dim, then proceed with the following electrical
tests.
CIRCUIT BREAKER TEST
Find correct circuit breaker on fuse block. Pull out
slightly but be sure that circuit breaker terminals still
contact terminals in fuse block. Connect ground wire of
voltmeter to a good ground. With probe of voltmeter
positive wire, check both terminals of circuit breaker
for battery voltage. If only one terminal checks at
battery voltage, circuit breaker is defective and must
be replaced. If neither terminal shows battery voltage,
check for open or shorted circuit to circuit breaker.
HARNESS VOLTAGE TEST
The following test will determine whether or not
voltage is continuous through the body harness to the
switch. (1) Remove power seat switch from mounting posi-
tion and disconnect switch from wiring harness. (2) Connect one lead of test light to ground terminal,
black wire (BK) of center section, and touch other test
light lead to red wire (RD) terminal. (3) If test light comes on, harness to switch is good.
If test light does not come on, perform circuit breaker
test.
MOTOR TESTS
AA BODY
(1) Remove switch from mounting position and dis-
connect from harness. (2) To check the center motor, connect a jumper wire
between pin 5 and pin 3 (Fig. 1). Connect a second
jumper wire between pin 7 and pin 4 If motor does not
operate, reverse the jumpers, pin 5 to pin 4 and pin 7 to
pin 3. If motor still does not operate check wiring
between switch connector and motor assembly. If wir-
ing checks good replace motor assembly. (3) To check the front motor, connect a jumper wire
between pin 5 and pin 1 (Fig. 1). Connect a second
jumper wire between pin 7 and pin 8. If motor does not
operate, reverse the jumpers, pin 5 to pin 8 and pin 7 to
pin 1. If motor still does not operate check wiring
between switch connector and motor assembly. If wir-
ing checks good replace motor assembly.
(4) To check the rear motor, connect a covered jumper
wire between pin 5 and pin 6 (Fig. 1). Connect a second
Ä POWER SEATS 8R - 1

jumper wire between pin 7 and 2.If motor does not op-
erate, reverse the jumpers, pin 5 to pin 2 and pin 7 to 6.
If motor still does not operate check wiring between
switch connector and motor assembly. If wiring checks
good replace motor assembly.
(5) If all motors and the seat operate properly, per-
form Switch Test.
AG & AJ BODIES
(1) Remove switch from mounting position and dis-
connect from harness. (2) To check the front motor, connect a jumper
wire between cavity number 2 and cavity number 9
(Fig. 2). Connect a second jumper wire between cav-
ity number 6 and cavity number 5. If the motor does
not operate, reverse the jumpers, 2 to 5 and 6 to 9. If
motor still does not operate check wiring between
switch connector and motor assembly. If wiring
checks good replace motor assembly. (3) To check the center motor, connect a jumper
wire between cavity number 2 and cavity number 8.
Connect a second jumper wire between cavity 6 and
cavity number 7. If the motor does not operate, re-
verse the jumpers, 2 to 7 and 6 to 8. If motor still
does not operate check wiring between switch con-
nector and motor assembly. If wiring checks good re-
place motor assembly. (4) To check the rear motor, connect a jumper be-
tween cavity number 2 and cavity number 10. Con-
nect a second jumper wire between cavity number 6
and cavity number 3. If the motor does not operate,
reverse the jumpers, 2 to 3 and 6 to 10. If motor still
does not operate, check wiring between switch con-
nector and motor assembly. If wiring checks good re-
place motor assembly. (5) To check the seat back recliner motor if
equipped, connect a jumper wire be tween cavity
number 2 and cavity number 1. Connect a second
jumper wire between cavity number 6 and cavity
number 11. If the motor does not operate, reverse the jumpers (2 to 11 and 6 to 1). If motor still does not
operate check wiring be tween switch connector and
motor assembly. If wiring checks good replace motor
assembly.
(6) If all motors and the seat operate properly, per-
form Switch Test.
AC AND AY BODIES
The following tests do not apply to left seat on ve-
hicles equipped with memory mirrors/seats. Refer to
test procedures for power memory mirrors/seats in
this section. (1) Remove switch from mounting position and dis-
connect from harness. (2) To check the front motor, connect a jumper
wire between cavity number 3 and cavity number 8
(Fig. 3 and 4). Connect a second jumper wire between
cavity number 6 and cavity number 7. If the motor
does not operate, reverse the jumpers, 3 to 7 and 6 to
8. If the motor still does not operate check the wiring
between switch connector and motor assembly. If
wiring checks good replace motor assembly. (3) To check the center motor, connect a jumper
wire between cavity number 3 and cavity number 5.
Connect a second jumper wire between cavity num-
ber 6 and cavity number 2. If the motor does not op-
erate, reverse the jumpers, 3 to 2 and 6 to 5. If the
motor still does not operate check the wiring between

wing. Refer to Owner Manual supplied with vehicle
for complete instructions for seat operation.
SWITCH TEST
For switch testing, remove switch from its mount-
ing location. Using an ohmmeter, refer to Figures 13
and 14 to determine if continuity is correct. If these
results are not obtained, replace the switch.
SWITCH REPLACEMENT REMOVAL
(1) Remove left cushion side shield.
(2) Disconnect wiring from switch.
(3) Depress bezel retainers and push switch from
bezel. (4) For installation, reverse above procedure.
POWER MEMORY SEAT, RECLINER AND
MIRRORS
AC & AY Body vehicles have, as an option, a spe-
cial 2 position memory power seat, recliner and
memory power outside rear view mirror system.
Each of the components can be moved to a desired
position by operating switches (Fig. 15). The seat and
recliner use potentiometers as position sensors and
the mirrors use rheostats to send their positioning
information back to the control module in the driv-
er's seat. After the desired seat and mirror position is
set. The seat, recliner, and mirror position can be
memorized at any time by pressing and release the
Set button. Followed by pressing the Position 1 or 2
button, for the specific position desired. DO NOT
press any other seat related switch for at least 5 sec-
onds. However, for the driver to recall a position, the
vehicle must not be moving and the seat belt must
NOT be buckled. Refer to the Owners Manual sup-
plied with the vehicle for complete instructions on
system operation.
