~ INSPECTION
I t!ll Remove the connectors of the front door lock
(& power window) switch, and check the
continuity and the voltage between the switch

inspection is found abnormal.
~ DOOR LOCK OPERATION TEST
ltUI After confirming tha~ there is continuity
between the harness s1de connector terminals
8l D-51 and 91 D-51 of the front door lock
switch-LH, apply battery voltage
to each of the
terminals to conduct the operation test. (Fig. 8-
187) When the
door lock will not operate, check
the
door lock actuator for any trouble.

DOOR LOCK ACTUATOR (FOR ALL
DOORS INCLUDING TAILGATE)
Receiving the forward or reverse current from the
front door lock (& power window) switch-LH, the
door lock actuator locks or unlocks the door with the
rod connected
to the door lock mechanism. (Fig. 8-
192)
Fig. 8-192
~ INSPECTION OF THE DOOR LOCK
ACTUATOR
Apply the battery voltage to the connector
terminals
of the door lock actuator to check the
operation. (Fig. 8-193)
When the
door lock actuator is checked on the
vehicle and there is no continuity, and when the
door lock actuator itself is checked and no
trouble is found, check the circuit between the
door lock actuator and the front door lock (&
power window) switch-LH for any failure.

8 -156 CHASSIS ELECTRICAL
POWER WINDOW
GENERAL DESCRIPTION I
The circuit consists of the starter switch, (door lock &) power window switch for each of the front wlndows,
power widow switch for rear windows and power window motors.
When the starter switch is
turned on, the battery voltage is applied to each of the power window switches
through the circuit breaker and the power window relay on the circuit. ,
The "DOWN" switch of the driver's power window switch has a built-in function which can be ope~ted by
just.t?uching it. Accordingly, the window will roll down automatically by just setting the switch to thf AUTO
pos1t1on. ,
When the driver's power lock switch at the driver side is depressed, the power source to the pas~enger's
power window switches are shut off. So, even if these switches are operated, the power window motor will
not operate.
