POWER WINDOWS

DESCRIPTION

Power windows are available as factory-installed

optional equipment on this model. The Remote Key-
less Entry (RKE) system and power lock system are
included on vehicles equipped with the power win-
dow option. For complete circuit diagrams, refer to
the appropriate wiring information. The wiring infor-
mation 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 con-
nectors, splices and grounds.

The power window system allows each of the door

windows to be raised and lowered electrically by
actuating a switch on the trim panel of each respec-
tive door. A master switch on the driver side front
door trim panel allows the driver to raise or lower
each of the passenger door windows and, on quad cab
models, to lock out the individual switches on the
passenger doors from operation. The power window
system

receives

battery

feed

through

circuit

breaker in the junction block, only when the ignition
switch is in the On position.

The power window system includes the power win-

dow switches on each door trim panel, the circuit
breaker in the junction block, and the power window
motors inside each door. This group covers diagnosis
and service of only the electrical components in the
power window system. For service of mechanical
components, such as the regulator, lift plate, window
tracks, or glass refer to Group 23 - Body.

Following are general descriptions of the major

components in the power window system. Refer to
the owner’s manual in the vehicle glove box for more
information on the features, use and operation of the
power window system.

OPERATION

POWER WINDOW SWITCH

On conventional cab and club cab models, the

power windows are controlled by two-way switches
integral to the power window and lock switch bezel
on the passenger side and the Driver Door Module on
the driver side of the trim panel of each front door. A
second power window switch in the driver side switch
and bezel unit allows the driver to control the pas-
senger side window. On quad cab models, the power
windows are controlled by four two-way switches and
a power window lockout switch that are integral to
the Driver Door Module on the driver side front door
trim panel. Additionally, each of the passenger doors
has a single gang two-way power window switch
mounted in a bezel on their respective door trim pan-
els.

On all models, the power window switch for the

driver side front door window has an Auto label on it.
This switch has a second detent position beyond the
normal Down position that provides an automatic
one-touch window down feature. This feature is con-
trolled by an electronic circuit and a relay that are
integral to the driver side front door power window
and lock switch unit.

The power window switches control the battery

and ground feeds to the power window motors. All of
the passenger door power window switches receive
their battery and ground feeds through the circuitry
of the driver side master switch unit. On quad cab
models, when the power window lockout switch is in
the Lock position, the battery feed for the individual
passenger door power window switches is inter-
rupted.

A Light-Emitting Diode (LED) in the paddle of

each switch is illuminated whenever the ignition
switch is in the On position. However, on quad cab
models the LEDs for the passenger power window
switches

are

extinguished

whenever

the

driver

selects the Lock position with the power window
lockout switch.

POWER WINDOW MOTOR

A permanent magnet reversible motor moves the

window regulator through an integral gearbox mech-
anism. A positive and negative battery connection to
the two motor terminals will cause the motor to
rotate

one

direction.

Reversing

the

current

through these same two connections will cause the
motor to rotate in the opposite direction.

In addition, each power window motor is equipped

with an integral self-resetting circuit breaker to pro-
tect the motor from overloads. The power window
motor and gearbox assembly cannot be repaired and,
if faulty or damaged, the entire power window regu-
lator assembly must be replaced.

CIRCUIT BREAKER

An automatic resetting circuit breaker in the junc-

tion block is used to protect the power window sys-
tem circuit. The circuit breaker can protect the
system from a short circuit, or from an overload con-
dition caused by an obstructed or stuck window glass
or regulator.

The circuit breaker cannot be repaired and, if

faulty, it must be replaced.

DIAGNOSIS AND TESTING - POWER
WINDOWS

For complete circuit diagrams, refer to the appro-

priate 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 connec-
tors, splices and grounds.

ALL WINDOWS INOPERATIVE

(1) Check the circuit breaker in the junction block,

as described in this group. If OK, go to Step 2. If not
OK, replace the faulty circuit breaker.

(2) Disconnect and isolate the battery negative

cable. Remove the power window and lock master
switch unit from the driver side front door trim
panel. Unplug the wire harness connector from the
master switch unit.

(3) Check for continuity between the ground cir-

cuit cavity of the power window and lock master
switch unit wire harness connector and a good
ground. If OK, go to Step 4. If not OK, repair the cir-
cuit to ground as required.

(4) Connect the battery negative cable. Turn the

ignition switch to the On position. Check for battery
voltage at the fused ignition switch output (run) cir-
cuit cavity of the power window and lock master

switch unit wire harness connector. If OK, (Refer to 8
- ELECTRICAL/POWER WINDOWS/POWER WIN-
DOW SWITCH - DIAGNOSIS AND TESTING). If not
OK, repair the circuit to the junction block as
required.

ONE WINDOW INOPERATIVE

The window glass must be free to slide up and

down for the power window motor to function prop-
erly. If the glass is not free to move up and down, the
motor will overload and trip the integral circuit
breaker. To determine if the glass is free, disconnect
the regulator plate from the glass. Then slide the
window up and down by hand.

There is an alternate method to check if the glass

is free. Position the glass between the up and down
stops. Then, shake the glass in the door. Check that
the glass can be moved slightly from side to side,
front to rear, and up and down. Then check that the
glass is not bound tight in the tracks. If the glass is
free, proceed with the diagnosis that follows. If the
glass is not free, refer to Group 23 - Body for the
door window glass and hardware service and adjust-
ment procedures.

If the only inoperative window is in the driver side

front door and the preceding checks have not identi-
fied a problem, (Refer to 8 - ELECTRICAL/POWER
WINDOWS/WINDOW MOTOR - DIAGNOSIS AND
TESTING). If the problem being diagnosed involves
only the Auto-down feature for the driver side front
door window, but all of the power windows are oper-
ational, replace the faulty Driver Door Module. If the
problem being diagnosed involves only an inoperative
power window switch Light-Emitting Diode (LED),
but the power window that the switch controls oper-
ates satisfactorily from that switch, replace the
faulty switch unit. For any other single power win-
dow problem proceed with diagnosis as follows:

(1) Disconnect and isolate the battery negative

cable. Unplug the wire harness connector from the
power window switch unit on the door with the inop-
erative power window. Check for continuity between
the ground circuit cavity of the power window switch
wire harness connector and a good ground. There
should be continuity. If OK, go to Step 2. If not OK,
repair the open circuit to the power window and door
lock master switch as required.

(2) Connect the battery negative cable. Turn the

ignition switch to the On position. Check for battery
voltage at the fused ignition switch output (run) cir-
cuit cavity in the body half of the power window
switch unit wire harness connector. If OK, go to Step
3. If not OK, repair the open circuit to the power
window and door lock master switch as required.

(3) Test the power window switch continuity (Refer

to 8 - ELECTRICAL/POWER WINDOWS/POWER

8N - 22

POWER WINDOWS

POWER WINDOWS (Continued)

WINDOW SWITCH - DIAGNOSIS AND TESTING) .
If OK, go to Step 4. If not OK, replace the faulty
power window switch unit.

(4) For complete circuit diagrams, refer to the

appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds. Check the continuity in
each circuit between the inoperative power window
switch wire harness connector cavities and the corre-
sponding power window motor wire harness connec-
tor cavities. If OK, (Refer to 8 - ELECTRICAL/
POWER

WINDOWS/WINDOW

MOTOR

DIAGNOSIS AND TESTING). If not OK, repair the
open circuit(s) as required.

NOTE: All passenger door power window switches
receive their battery and ground feed for operating
the passenger door power window motors through
the driver side power window and lock master
switch and wire harness connector.

CIRCUIT BREAKER

For complete circuit diagrams, refer to the appro-

(1) Locate the circuit breaker in the junction block.

Pull out the circuit breaker slightly, but be certain
that the circuit breaker terminals still contact the
terminals in the junction block cavities.

(2) Connect the negative lead of a 12-volt DC volt-

meter to a good ground.

(3) With the voltmeter positive lead, check both

terminals of the circuit breaker for battery voltage.

If only one terminal has battery voltage, the circuit

breaker is faulty and must be replaced. If neither ter-
minal has battery voltage, repair the open circuit
from

the
