LUMBAR CONTROL SWITCH
DESCRIPTION
The power lumbar seat option includes an electri-
cally operated lumbar support mechanism. A single
two-way momentary power lumbar switch is integral
with the power seat switches. The power lumbar
switch is secured to the back of the seat cushion side
shield with screws, and the switch paddle protrudes
through a hole to the outside of the shield. The
switch paddle is located in a shallow depression
molded into the outer surface of the seat cushion side
shield that helps to shroud it from unintentional
actuation when entering or leaving the vehicle.
The power lumbar switches cannot be adjusted or
repaired and, if faulty or damaged, the seat switch
assembly must be replaced.

OPERATION
When the power lumbar switch paddle is actuated,
a battery feed and a ground path are applied through
the switch contacts to the power lumbar adjuster
motor. The motor operates to move the lumbar
adjuster through its drive unit in the selected direc-
tion until the switch is released, or until the travel
limit of the adjuster is reached. When the switch is
moved in the opposite direction, the battery feed and
ground path to the motor are reversed through the
switch contacts. This causes the motor to run in the
opposite direction.
The power lumbar switch should not be held
applied in either direction after the adjuster has
reached its travel limit. The power lumbar adjuster
motor contains a self-resetting circuit breaker to pro-
tect it from overload. However, consecutive or fre-
quent resetting of the circuit breaker must not be
allowed to continue, or the motor may be damaged.
REMOVAL
The power lumbar switch is integral with the other
power seat switches. Refer to the appropriate driver
or passenger power front seat switch removal and/or
installation procedure.
LUMBAR MOTOR
DESCRIPTION
The power lumbar seat option includes an electri-
cally operated lumbar support mechanism. The only
visible evidence of this option is the separate power
lumbar switch control paddle that is located on the
outboard seat cushion side shield, next to the other
power seat switch control knobs. The power lumbar
adjuster and motor are concealed beneath the seat
back trim cover and padding, where they are secured
to a molded plastic back panel and to the seat back
frame.
The power lumbar adjuster cannot be repaired, and
is serviced only as a unit with the seat back frame. If
the power lumbar adjuster or the seat back frame
are damaged or faulty, the entire seat back frame
unit must be replaced (Refer to 23 - BODY/SEATS/
SEAT BACK - REMOVAL).
OPERATION
The power lumbar adjuster mechanism includes a
reversible electric motor that is secured to the
inboard side of the seat back panel and is connected
to a worm-drive gearbox. The motor and gearbox
operate the lumbar adjuster mechanism in the center
of the seat back by extending and retracting a cable
that actuates a lever. The action of this lever com-
presses or relaxes a grid of flexible slats. The morethis grid is compressed, the more the slats bow out-
ward against the center of the seat back padding,
providing additional lumbar support.
DIAGNOSIS AND TESTING - LUMBAR MOTOR
Actuate the power lumbar switch to move the
power lumbar adjuster in each direction. The power
lumbar adjuster should move in both directions. It
should be noted that the power lumber adjuster nor-
mally operates very quietly and exhibits little visible
movement. If the power lumbar adjuster fails to oper-
ate in only one direction, move the adjuster a short
distance in the opposite direction and test again to be
certain that the adjuster is not at its travel limit. If
the power lumbar adjuster still fails to operate in
only one direction, (Refer to 8 - ELECTRICAL/
POWER SEATS/DRIVER SEAT SWITCH - DIAGNO-
SIS AND TESTING). If the power lumbar adjuster
fails to operate in either direction, perform the fol-
lowing tests. For complete circuit diagrams, refer to
Wiring Diagrams.
(1) Check the power seat circuit breaker in the
junction block. If OK, go to Step 2. If not OK, replace
the faulty power seat circuit breaker.
(2) Check for battery voltage at the power seat cir-
cuit breaker in the junction block. If OK, go to Step
3. If not OK, repair the open fused B(+) circuit to the
fuse in the Power Distribution Center as required.
(3) Remove the outboard seat cushion side shield
from the seat. Disconnect the seat wire harness con-
nector from the power lumbar switch connector
receptacle. Check for battery voltage at the fused
B(+) circuit cavity of the power seat wire harness
connector for the power lumbar switch. If OK, go to
Step 4. If not OK, repair the open fused B(+) circuit
to the power seat circuit breaker in the junction
block as required.
(4) Check for continuity between the ground cir-
cuit cavity of the power seat wire harness connector
for the power lumbar switch and a good ground.
There should be continuity. If OK, go to Step 5. If not
OK, repair the open ground circuit to ground as
required.
(5) Test the power lumbar switch. . If the switch
tests OK, test the circuits of the power seat wire har-
ness between the power lumbar adjuster motor and
the power lumbar switch for shorts or opens. If the
circuits check OK, replace the faulty seat back frame
assembly. If the circuits are not OK, repair the power
seat wire harness as required.

DESCRIPTION
The power seat in standard cab models can be
adjusted in eight different directions, up, down, front
up, front down, rear up, rear down, rearward and for-
ward.

PASSENGER POWER SEAT
SWITCH
DESCRIPTION
The power seat in standard cab models can be
adjusted in eight different directions, up, down, front
up, front down, rear up, rear down, rearward and for-
ward. The power seat switch for quad cab models has
an additional switch knob for adjusting the power
lumbar support. The switch is located on the lower
outboard side of the seat cushion on the seat cushion
side shield (Fig. 5) on all models. Refer to the owner's
manual in the vehicle glove box for more information
on the power seat switch functions and the seat
adjusting procedures.
The individual switches in the power seat switch
module cannot be repaired. If one switch is damaged
or faulty, the entire power seat switch module must
be replaced.
OPERATION
When a power switch control knob or knobs are
actuated, a battery feed and a ground path are
applied through the switch contacts to the power seat
track or recliner adjuster motor. The selected
adjuster motor operates to move the seat track or
recliner through its drive unit in the selected direc-
tion until the switch is released, or until the travel
limit of the adjuster is reached. When the switch is
moved in the opposite direction, the battery feed and
ground path to the motor are reversed through the
switch contacts. This causes the adjuster motor to
run in the opposite direction.No power seat switch should be held applied in any
direction after the adjuster has reached its travel
limit. The power seat adjuster motors each contain a
self-resetting circuit breaker to protect them from
overload. However, consecutive or frequent resetting
of the circuit breaker must not be allowed to con-
tinue, or the motor may be damaged.
DIAGNOSIS AND TESTING - PASSENGER
POWER SEAT SWITCH
The following procedure can be used to test the
power seat switch on standard and quad cab models.
Some quad cab trucks utilize a additional power lum-
bar option, if the switch being tested does not have
the lumbar option simply ignore the lumbar portion
of the test. For circuit descriptions and diagrams,
refer to Wiring Diagrams.
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the power seat switch from the power
seat.
(3) Use an ohmmeter to test the continuity of the
power seat switches in each position. See the Power
Seat Switch Continuity chart below (Fig. 6). If OK,
see Power Seat Adjuster and Motors or Power Lum-
bar Adjuster and Motor in the Diagnosis and Testing
section of this group. If not OK, replace the faulty
power seat switch unit.

POWER SEAT TRACK
DESCRIPTION
There are three reversible motors that operate the
power seat adjuster. The motors are connected to
worm-drive gearboxes that move the seat adjuster
through a combination of screw-type drive units.
The front and rear of a seat are operated by differ-
ent motors. They can be raised or lowered indepen-
dently of each other. When the center seat switch is
pushed in the Up or Down direction, both the front
and rear motors operate in unison. On standard cab
models the entire seat is moved up or down, on quad
cab models the seat cushion moves independently of
the seat back in the up or down directions. The for-
ward-rearward motor is operated by pushing the cen-
ter seat switch in the Forward or Rearward direction,
which moves the entire seat in the selected direction
on all models.

Each motor contains a self-resetting circuit breaker
to protect it from overload. Consecutive or frequent
resetting of the circuit breakers must not be allowed
to continue, or the motors may be damaged.
The power seat adjuster and motors cannot be
repaired, and are serviced only as a complete unit. If
any component in this unit is faulty or damaged, the
entire power seat adjuster and motors assembly must
be replaced.
OPERATION
When a power seat switch is actuated, a battery
feed and a ground path are applied through the
power seat switch contacts to the appropriate motor
or motors. The motor and drive unit operate to move
the seat in the selected direction until the switch is
released, or until the travel limit of the power seat
track is reached. When the switch is moved in the
opposite direction, the battery feed and ground path
to the motor is reversed through the switch contacts.
This causes the motor to run in the opposite direc-
tion.
DIAGNOSIS AND TESTING - POWER SEAT
TRACK
For complete power seat circuit descriptions and
diagrams, refer to Wiring Diagrams.
Operate the power seat switch to move all three
seat motors in each direction. The seat should move
in each of the selected directions. If the power seat
track fails to operate in only one direction, move the
seat track a short distance in the opposite direction
and test again to be certain that the track is not at
its travel limit. If the power seat track still fails to
operate in only one direction, refer to Diagnosis and
Testing of the Power Seat Switch in this section. If
the power seat track fails to operate in more than
one direction, proceed as follows:
(1) Check the power seat fuse in the power distri-
bution center. If OK, go to Step 2. If not OK, replace
the faulty fuse.
(2) Remove the power seat switch from the seat.
Check for battery voltage at the fused B(+) circuit
cavity of the power seat switch wire harness connec-
tor. If OK, go to Step 3. If not OK, repair the open
circuit to the power distribution center as required.(3) Check for continuity between the ground cir-
cuit cavity of the power seat switch wire harness con-
nector and a good ground. There should be
continuity. If OK, go to Step 4. If not OK, repair the
open circuit to ground as required.
(4) Test the power seat switch as described in this
group. If the switch tests OK, check the wire harness
between the power seat switch and the motor for
shorts or opens. If the circuits check OK, replace the
faulty power seat track (adjuster) assembly. If the
circuits are not OK, repair the wire harness as
required.

POWER WINDOWS
DESCRIPTION
Power windows are available as factory-installed
optional equipment on this model. The power lock
system is included on vehicles equipped with the
power window option.
OPERATION
The power window system allows each of the front
door windows to be raised and lowered electrically by
actuating a switch on the trim panel of each respec-
tive door. Additionally, the master switch on the
driver side door trim panel allows the driver to raise
or lower the passenger side front door window. The
power window system receives battery feed through a
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 front door trim panel, the cir-
cuit breaker in the junction block, and the power
window motors inside each front 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.
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.
DIAGNOSIS AND TESTING - POWER
WINDOWS
For circuit descriptions and diagrams, refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harnessrouting and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.
ALL WINDOWS INOPERATIVE
(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) Disconnect and isolate the battery negative
cable. Remove the power window and lock switch and
bezel unit from the driver side front door trim panel.
Unplug the wire harness connector from the switch
and bezel unit.
(3) Check for continuity between the ground cir-
cuit cavity of the switch and bezel unit wire harness
connector and a good ground. If OK, (Refer to 8 -
ELECTRICAL/POWER WINDOWS/POWER WIN-
DOW SWITCH - DIAGNOSIS AND TESTING). If not
OK, repair the circuit to ground 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 23 - BODY/DOOR -

required.
NOTE: The passenger side power window switch
receives the ground feed for operating the passen-
ger side power window motor through the driver
side power window switch and wire harness con-
nector.
POWER WINDOW SWITCH
DESCRIPTION
The power windows are controlled by two-way
switches integral to the power window and lock
switch and bezel unit on the trim panel of each frontdoor. A second power window switch in the driver
side switch and bezel unit allows the driver to control
the passenger side window. A Light-Emitting Diode
(LED) in the paddle of each switch is illuminated
whenever the ignition switch is in the On position.
OPERATION
The power window switch for the driver side front
door has an Auto label on it. This switch has a sec-
ond detent position beyond the normal Down position
that provides an automatic one-touch window down
feature. This feature is controlled 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. The
passenger side power window switch receives a
ground feed through the driver side power window
switch for operating the passenger side power win-
dow motor.
The power window and lock switch and bezel unit
cannot be repaired and, if faulty or damaged, the
entire switch and bezel unit must be replaced.
DIAGNOSIS AND TESTING - POWER WINDOW
SWITCH
The auto down feature of the driver side power
window switch is controlled by an electronic circuit
within the switch unit. The auto down circuitry is
activated when the driver side power window switch
is moved to the second detent in the Down direction.
The outputs from the auto down circuitry are carried
through the same switch pins that provide the nor-
mal down function. The auto down circuit cannot be
tested. If the driver side power window switch conti-
nuity tests are passed, but the auto down feature is
inoperative, replace the faulty driver side power win-
dow switch unit.
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
either or both power window and lock switch and
bezel units and the power windows are inoperative,
perform the diagnosis for Power Window System in
this group. If the power windows operate, but any or
all of the LEDs are inoperative, the power window
and lock switch and bezel unit with the inoperative
LED(s) is faulty and must be replaced. For circuit
descriptions and diagrams, 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
