ELECTRIC MOTOR TEST
Make certain battery is in normal charged condi-
tion before circuits are tested. To determine which motor is faulty, check each in-
dividual door for electrical lock and unlock or discon-
nect the motor connectors one at a time, while
operating the door lock switch. In the event that
none of the motors work, the problem maybe caused
by a shorted motor, or a bad switch. Disconnecting
the defective motor will allow the others to work. The power lock motors are also equipped with a
thermal protection system which prevents the motors
from burning out. The motors may chatter if they are
continuously activated. To test an individual door lock motor, disconnect
the wire connector at the motor (Fig. 2 and 3). Test
at the connector for 12 volts while applying door lock
switch. If no voltage repair wire. Apply 12 volts to
the motor terminal, and a known good ground to the
other terminal to check motor operation. Should the motor defect be a result of a broken
wire, it should have no effect on the operation of the
other motors.
POWER DOOR LOCKS
When AC, AG, AJ or AY Body vehicles are
equipped with power door locks, the system includes
an automatic door locking feature which is actuated
through the vehicle's body controller. When this system is enabled the automatic door
locks will work automatically. When the system is
disabled the door locks will work by use of the door
lock switches only. The body controller controls the power locks when
the door lock switch is activated. If the door lock switch is pressed for longer than eight consecutive
seconds, the body controller will de-energize the door
lock relay. Also, the body controller will automati-
cally lock all doors when all of the conditions below
are met:
² All doors are closed
² The vehicle speed exceeds 15 61 MPH
² The throttle position sensor tip-in is greater than
10 62 degrees
The DRB II must be used to enable/disable the au-
tomatic door lock system. Refer to the Body Diagnos-
tic Procedures Manual for the procedure. The body controller will automatically re-lock all
doors if the above conditions are met and if any of
the doors become ajar. The body controller does not
control the door unlock function. The switch is wired
directly to the lock relay.

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.

ity 9 and pin 7 of the control module 25-way connec-
tor. The vehicle speed sensor signal can be tested
with a volt/ohmmeter at pin 7 of the control module
25-way connector. Turn on the vehicle ignition and
check fo r a 5 volt signal as the vehicle is moved
about 3 to 5 feet. If not repair open wiring, terminal
push out, bad crimp, drive in vehicle speed sensor,
etc., as necessary to correct condition. Ensure that
the 25-way connector is plugged into the control
module securely. Road test vehicle after repairs have
been made to ensure that no recalls can occur while
moving.
CONDITION: INSTRUMENT CLUSTER SPEEDOMETER STAYS AT 0 MPH/ (0 KM/H)WHILE VEHICLE IS MOVING, BODYCOMPUTER DOES NOT LOCK DOORS AT 15MPH (24 KM/H), AND THE SPEED CONTROLWILL NOT ACCEPT A SPEED SET.
PROCEDURE
(1) Remove driver's seat anchor bolts and nuts. Ad-
just the driver's seat to a safe driving position. Dis-
connect the 25-way connector from the memory seat
control module. Replace the driver's seat anchor bolts
and nuts. Road test the vehicle to complete this diag-
nosis. If the doors lock, the cruise control accepts a
set, and the speedometer now works, replace the
Memory Seat control module. (2) After replacing the Memory Seat control mod-
ule, perform the memory seat diagnostic self tests.
This teaches the new module it's soft limits and now
re-road test the vehicle before returning it to the cus-
tomer.
CONDITION: NO SEAT MOVEMENT IN THE RECALL MODE, SEAT WILL MOVE BYMANUAL SWITCH ACTUATION IN ALLDIRECTIONS WITHOUT STALL DETECTION.
PROCEDURE
(1) Check for 5 volts at pin 10 of the control mod-
ule 25-way connector. This is the 5 volt feed from the
control module to the seat track position sensing po-
tentiometer. (2) Check for ground at pin 8 of the control module
25-way connector. To test for ground, one lead of the
voltmeter must be connected to either the 5 volt sup-
ply for the control module or the battery positive. If
the sense voltage and ground are NOT present at the
above pins of the 21-way control module connector.
When the seat switch is pressed, replace the control
module. An inadvertent application of battery volt-
age to the circuit could damaged the control module.
If the voltage and ground circuits are present then
continue this procedure. (3) Check for 5 volts at pin 5 of the natural 5-way
connector plugged into the power seat adjuster mo-
tors end-bell. (4) Check for ground at pin 4 of the natural 5-way
connector plugged into the power seat adjuster mo-
tors end-bell. If the power seat adjuster still has no
movement in the recall mode, then continue this pro-
cedure. (5) Disconnect the natural 5-way connector from
the power seat adjuster motors end-bell. (6) Check with an ohmmeter for a resistance read-
ing that may be from 2600 to 4000 ohms between
pins 4 and 5 of the motors end-bell connector. If
there is an open circuit reading or the reading ob-
tained falls outside this range, then replace the seat
motor package assembly. After replacement of the
seat motor package, reconnect all wiring connectors
and reinstall seat assembly in vehicle. Operate the
switches manually to cause maximum seat move-
ment in all directions. Perform the memory seat di-
agnostic self check so the control module will learn
the new soft limits of the assembly.
CONDITION: NO SEAT TRACK FORWARD OR REARWARD MOVEMENT IN THE RECALLMODE, SEAT TRACK WILL MOVE FORWARDOR REARWARD BY MANUAL SWITCHACTUATION WITHOUT STALL DETECTION.
PROCEDURE
(1) Check for a voltage at pin 12 of the control
module 21-way connector. Less than 5 volts for the
seat track fully forward and more than 0 volts when
fully rearward. This voltage should vary correspond-
ing to the position. (2) Check for a voltage at pin 1 of the natural
5-way connector, Same as in step (1) above. The
ground lead connected to pin 4 of the 5-way connec-
tor. If the voltage reading is at 0 volts, disconnect
the 5-way natural connector and check for a short to
ground in the harness. If no short is found, reconnect
the connector and continue the procedure. (3) Check for the voltage to vary as noted above, if
it does not vary as the seat track is moved forward
and rearward, the sensing potentiometer is defective.
Replace the seat motor package assembly. After re-
placement of the seat motor package, reconnect all
wiring connectors and reinstall seat assembly in ve-
hicle. Operate the switches manually to cause maxi-
mum seat movement in all directions. Perform the
memory seat diagnostic self check so the control
module will learn the new soft limits of the assem-
bly.

² Turn ignition switch to the ON position with the
vehicle in park (Fig. 21).
² Place mirror switch in the high position.
² Cover the forward facing sensor with dark cloth to
keep out any ambient light.
² Shine a light into the rear facing sensor, watch to
see if the mirror darkens. With the mirror darkened, place the vehicle in re-
verse, the mirror should return to its normal condi-
tion. If the above conditions are met the mirror is oper-
ating properly.
² If not test voltage.
Test three way connector harness. Refer to Fig. 21. (1) Pin 1 Ignition Switch in run position, should
have battery voltage. (2) Pin 2 Should have continuity to Ground.
