QUAD CAB
The
Light-Emitting
Diode
(LED)
illumination
lamps for all of the power window and lock switch
and bezel unit switch paddles receive battery current
through the power window circuit breaker in the
junction block. If all of the LEDs are inoperative in
both the power window and lock switch units and the
power windows are inoperative, (Refer to 8 - ELEC-
TRICAL/POWER WINDOWS - DIAGNOSIS AND
TESTING). If the power windows operate, but any or
all of the LEDs are inoperative, the power window
and lock switch units with the inoperative LED(s) is
faulty and must be replaced. For complete circuit dia-
grams, refer to the appropriate wiring information.
The wiring information includes wiring diagrams,
proper wire and connector repair procedures, details
of wire harness routing and retention, connector pin-
out information and location views for the various
wire harness connectors, splices and grounds.
(1) Check the circuit breaker in the junction block.
If OK, go to Step 2. If not OK, replace the faulty cir-
cuit breaker.
(2) Turn the ignition switch to the On position.
Check for battery voltage at the circuit breaker in
the junction block. If OK, turn the ignition switch to
the Off position and go to Step 3. If not OK, repair
the circuit to the ignition switch as required.
(3) Disconnect and isolate the battery negative
cable. Remove the power window switch unit from
the door trim panel (passenger doors only). For diag-
nosis of the driver side power window switch (Refer
to 8 - ELECTRICAL/POWER LOCKS/DOOR MOD-
ULE - DIAGNOSIS AND TESTING). Unplug the
wire harness connector from the switch unit.
(4) Test the power window switch continuity. See
the Power Window Switch Continuity chart to deter-
mine if the continuity is correct in the Off, Up and
Down switch positions (Fig. 2). If OK, (Refer to 8 -
ELECTRICAL/POWER
WINDOWS/WINDOW
MOTOR - DIAGNOSIS AND TESTING). If not OK,
replace the faulty switch.

CAL/POWER LOCKS/DOOR MODULE - REMOVAL)
for the service procedures.
(1) Disconnect and isolate the battery negative
cable.
(2) Using a trim stick, start at the rear of the
switch bezel and pry up from door trim panel .
(3) Disconnect the wire harness connector from
switch.
(4) Remove switch from bezel.
INSTALLATION
The driver side power window switch is included
with the Drive Door Module. (Refer to 8 - ELECTRI-
CAL/POWER LOCKS/DOOR MODULE - INSTALLA-
TION) for the service procedures.
(1) Install switch to bezel.
(2) Connect wire harness connector to switch.
(3) Insert the front of the switch into the door trim
panel first, then press into position.
