GENERAL
Door lock actuators are controlled by two rocker
switches. To lock doors, push down on either switch. To
unlock doors from inside the vehicle push upward on
either switch.
The power door locks do not lock or unlock the doors
from outside the vehicle. Insert the key into the lock
cylinder to lock or unlock each individual door.
CIRCUITRY
The power door lock operates with battery power and,
therefore, is independent of the ignition switeh.
A 30-amp circuit breaker mounted in the fuse block
protects the circuit. Refer to wiring diagrams in the
back of this manual for complete circuits. The front door
harness runs from door to door and is secured to the
dash panel with harness retainers.
On four-door models, the right and left rear door
harnesses are connected to the front door harness at the
top of the side-cowl panels. They are routed along the
side sill to the B-pillar, then through the bottom of the
B-pillar to the rear doors.
If the vehicle is equipped with power windows, the
door lock wires become part of the combined wire har
nesses. The wire routing still follows the above des
cription.
Circuit Breaker Test
Disconnect harness connector from fuse panel. Test
fuse panel connection with test lamp. If lamp lights,
battery voltage is present. If no battery voltage is pre
sent, remove circuit breaker and test with ohmmeter. If
circuit breaker is OK then check for battery voltage at
circuit breaker connection on fuse panel. If no battery
voltage at fuse panel check for failure of fuse links in
engine compartment.
Switch Test
Test door switches for continuity with a self-powered
Test Lamp J-21008, or ohmmeter. Continuity should
exist between terminals at various switch positions as
shown in figure 3J-10.

they snap into position.
(2) Connect wiring to switch.
(3) Install housing into door panel.
(4) Install watershield and trim panel.
(5) Connect negative battery cable.
ACTUATOR MOTOR
Test
To test the actuator motor, attach an ammeter to the
motor terminals and operate the door switch. Replace
the actuator motor if current draw exceeds 8 amps at
room temperature or if the actuator does not complete
its travel in less than one second.
Replacement
(1) Disconnect battery negative cable.
(2) Remove door trim panel and watershield.
