hazard switch button is visible through a dedicated,
round, beveled opening on the outer surface of the
instrument panel between the two center panel out-
lets of the heater and air conditioning system. A red,
stencil-like International Control and Display Symbol
icon for ªHazard Warningº identifies the hazard
switch button. On the opposite end of the black,
molded plastic hazard switch module housing from
the switch button is an integral connector receptacle
and a stamped steel mounting bracket with two latch
feature tabs that extend downward, while a short
dowel-like alignment pin is integral to each side of
the housing just below the switch button. The switch

HEADLAMP HIGH BEAM
RELAY
DESCRIPTION
The headlamp high beam relay is located in the
Junction Block (JB) on the driver side outboard end
of the instrument panel in the passenger compart-
ment of the vehicle. The headlamp high beam relay
is omitted from vehicles manufactured for sale in
Canada, which have a Daytime Running Lamp (DRL)
solid state relay installed in the JB that also per-
forms the function of the headlamp high beam relay.
The headlamp high beam relay is a conventional
International Standards Organization (ISO) micro
relay (Fig. 28). Relays conforming to the ISO specifi-
cations have common physical dimensions, current
capacities, terminal patterns, and terminal functions.
The relay is contained within a small, rectangular,molded plastic housing and is connected to all of the
required inputs and outputs by five integral male
spade-type terminals that extend from the bottom of
the relay base.
The headlamp high beam relay cannot be adjusted
or repaired and, if faulty or damaged, the unit must
be replaced.
OPERATION
The headlamp high beam relay is an electrome-
chanical switch that uses a low current input from
the Body Control Module (BCM) to control a high
current output to the headlamp high beam filaments.
The movable common feed contact point is held
against the fixed normally closed contact point by
spring pressure. When the relay coil is energized, an
electromagnetic field is produced by the coil wind-
ings. This electromagnetic field draws the movable
relay contact point away from the fixed normally
closed contact point, and holds it against the fixed
normally open contact point. When the relay coil is
de-energized, spring pressure returns the movable
contact point back against the fixed normally closed
contact point. A resistor is connected in parallel with
the relay coil in the relay, and helps to dissipate volt-
age spikes and electromagnetic interference that can
be generated as the electromagnetic field of the relay
coil collapses.
The headlamp high beam relay terminals are con-
nected to the vehicle electrical system through a con-
nector receptacle in the Junction Block (JB). The
inputs and outputs of the headlamp high beam relay
include:
²Common Feed Terminal- The common feed
terminal (30) receives battery current at all times
from a fuse in the Power Distribution Center (PDC)
through a fused B(+) circuit.
²Coil Ground Terminal- The coil ground termi-
nal (85) is connected to a control output of the Body
Control Module (BCM) through a head lamp relay
control circuit. The BCM controls head lamp opera-
tion by controlling a ground path through this circuit
²Coil Battery Terminal- The coil battery ter-
minal (86) is connected to a control output of the
Body Control Module (BCM) and to the momentary
optical horn (flash-to-pass) output of the multi-func-
tion switch through a high beam relay control circuit.
The BCM and/or the multi-function switch controls
headlamp high beam operation by controlling a
ground path through this circuit.
²Normally Open Terminal- The normally open
terminal (87) is connected to the headlamp high
beam filaments through the high beam relay output
circuit and provides battery current to the headlamp
high beams whenever the relay is energized.

HEADLAMP LEVELING MOTOR
DESCRIPTION
The headlamp leveling motor is located on the rear
inboard side of each headlamp unit on models
equipped with the headlamp leveling system, which
is available only in certain markets where required
(Fig. 31). The motor is encased within a molded plas-
tic housing and is secured by an integral wedge-type
mounting boss on its forward surface to a flanged
receptacle on the back of the headlamp unit housing.
A rubber seal around the circumference of the
mounting boss is compressed and seals the motor to
the headlamp unit when the boss is properly
installed in the flanged receptacle. The outside of the
motor housing features an integral molded connector
receptacle on its rearward surface, a hex-headed
adjusting screw extends from the top of the housing,
and a plastic pushrod with a ball formation on its
free end extends from the center of the mounting
boss at the front. Within the motor housing is a
12-volt Direct Current (DC) servo motor, an elec-
tronic controller board that includes the motor logic
circuits, and an integral screw-drive transmission.
The headlamp leveling motor is connected to the
vehicle electrical system through a dedicated take
out and connector of the front fascia wire harness.
The headlamp leveling motor cannot be repaired
and, if faulty or damaged, the unit must be replaced.

HEADLAMP LEVELING
SWITCH
DESCRIPTION
The headlamp leveling switch (Fig. 34) is used only
on vehicles manufactured for certain markets where
the headlamp leveling system is required. The head-
lamp leveling switch is mounted in the driver side
inboard trim bezel on the instrument panel, where it
is secured by molded latch features that are integral
to the switch housing. Only the switch bezel and
thumbwheel are visible on the outer surface of the
instrument panel trim bezel. The black plastic switch
thumbwheel is marked with white numbers ª0,º ª1,º
ª2,º and ª3,º each of which indicates one of the four
switch detent positions. Each higher number repre-sents a lower aiming position of the headlamp beam
relative to the road surface. The black, molded plas-
tic switch housing has an integral connector recepta-
cle on the back, a single latch feature on the top, and
two latch features (one on each side) on the bottom.
The switch is connected to the vehicle electrical sys-
tem through a dedicated take out and connector of
the instrument panel wire harness. Within the
switch housing is the leveling switch circuitry includ-
ing the switch contacts and a series resistor configu-
ration.
The headlamp leveling switch cannot be adjusted
or repaired and, if faulty or damaged, the unit must
be replaced.
OPERATION
The headlamp leveling switch receives battery cur-
rent on a fused park lamp relay output circuit from a
fuse in the Junction Block (JB) whenever the park
lamp relay is energized (park lamps are turned On).
The switch receives a path to ground through a splice
block located in the instrument panel wire harness
with an eyelet terminal connector that is secured by
a nut to a ground stud on the driver side instrument
panel end bracket near the JB. The only output from
the switch is a voltage signal that it provides to the
headlamp leveling motors on a headlamp adjust sig-
nal circuit. Each switch position selects a different
tap on a series resistor within the switch to provide a
different voltage signal to the leveling motors. The
higher the switch position number, the higher the
output voltage level.
The headlamp leveling switch can be tested using
conventional diagnostic tools and methods.

HEADLAMP LOW BEAM RELAY
DESCRIPTION
The headlamp low beam relay is located in the
Junction Block (JB) below the driver side outboard
end of the instrument panel in the passenger com-
partment of the vehicle. The headlamp low beam
relay is a conventional International Standards
Organization (ISO) micro relay (Fig. 37). Relays con-
forming to the ISO specifications have common phys-
