POWER LOCK MOTOR
(1) Once it is determined which lock motor is inop-
erative, that motor can be tested. Disconnect the wire
connector at the motor. Apply 12 volts to the motor
terminals to check its operation in one direction. Re-
verse the polarity to check the operation in the other
direction. If OK, repair circuits to power lock/unlock
relays as required. If not OK, replace the motor.
(2) If all lock motors are inoperative, the problem
may be caused by one shorted motor. Disconnecting a
shorted motor will allow the good motors to operate.
Disconnect each motor connector, one at a time, and
re-check both lock and unlock functions while operat-
ing the door lock switch. If disconnecting one motor
causes the other motors to become functional, go
back to step 1 to test the disconnected motor.
KEYLESS ENTRY TRANSMITTER
(1) Depress either transmitter button and note
whether red Light-Emitting Diode (LED) on trans-
mitter case lights. If OK, go to next step. If not OK,
replace batteries as described under Keyless Entry
Transmitter in Service Procedures. Test transmitter
operation. If OK, discard faulty batteries. If not OK,
go to next step.
(2) Perform transmitter program procedure with
suspect transmitter and another known good trans-
mitter, as described in Service Procedures. Test oper-
ation with both transmitters. If both transmitters fail
to operate power locks, see Keyless Entry Module di-
agnosis. If known good transmitter operates power
locks and suspect transmitter does not, replace faulty
transmitter. Be certain to perform transmitter pro-
gram procedure again when replacing faulty trans-
mitter and to erase test transmitter access code from
keyless entry module.
KEYLESS ENTRY MODULE
(1) Check fuse 9 in fuseblock module. If OK, go to
next step. If not OK, replace fuse.
(2) Check for battery voltage at fuse 9. If OK, go to
next step. If not OK, repair circuit from power distri-
bution center.
(3) Access keyless entry module connectors as de-
scribed in Keyless Entry Module Remove/Install.
(4) Unplug module connector from module. Check
connector and receptacle in module for loose, cor-
roded, or damaged terminals and pins. If OK, go to
next step. If not OK, repair as required.
(5) Probe connector cavity for module terminal 1
and check for battery voltage. If OK, go to next step.
If not OK, repair circuit to fuse 9 as required.
(6) Install a jumper wire from connector cavity for
module terminal 1 to connector cavity for module ter-
minal 3. Doors should lock. If OK, go to step 8. If not
OK, go to next step.
(7) Check for continuity between connector cavity
for module terminal 3 and lock relay terminal 3 (86).
There should be continuity. If OK, replace lock relay.
If not OK, repair circuit as required.
(8) Install a jumper wire from connector cavity for
module terminal 1 to connector cavity for module ter-
minal 4. Doors should unlock. If OK, replace module.
If not OK, go to next step.
(9) Check for continuity between connector cavity
for module terminal 4 and unlock relay terminal 3
(86). There should be continuity. If OK, replace un-
lock relay. If not OK, repair circuit as required.

SERVICE PROCEDURES
KEYLESS ENTRY TRANSMITTER
To replace transmitter batteries, separate transmit-
ter case by prying gently with a trim stick or other
wide flat-bladed tool at center seam (Fig. 2). Case
snaps open and shut. Replace with CR1616 3-volt
batteries or equivalent (Fig. 3).
TRANSMITTER PROGRAMMING PROCEDURE
(1) Open the driver's door of the vehicle. Leave it
open through the programming procedure.
(2) Move the mechanical door lock lever to the
LOCK position.
(3) Turn the ignition switch to the ON position.
(4) Within 20 seconds, aim a transmitter at the
keyless entry module receiver dome and press the
LOCK button for at least 5 seconds. Once the module
accepts the programming code, the driver's door will
unlock.
(5) Once the first transmitter has been pro-
grammed, additional transmitters (up to 4) may beprogrammed into the module. Within 20 seconds of
the previous transmitter programming, move the me-
chanical door lock lever to the LOCK position. Aim
another transmitter at the receiver dome and press
the LOCK button for at least 5 seconds. The door
lock will cycle again.
(6) To lock the programmed codes into the module,
the ignition switch must be turned OFF and back
ON within 20 seconds after programming the last
transmitter's code. At that time, all previous codes
are erased from the module.
POWER LOCK SWITCH REMOVE/INSTALL
(1) Remove the interior door latch release assem-
bly and control panel retaining screws (Fig. 4).
(2) Disconnect the control linkage and the wire
harness connector.
(3) Remove the latch release and control panel as-
sembly.
(4) The switch is retained to the panel with clips
(Fig. 5). Push in on the retainer part of the clip and
pry the clips.
(5) To install switch, position switch and press in
retainer clips until they snap into position. Reverse
remaining removal procedures to complete installa-
tion.
