FRONT FOG LAMP RELAY
DESCRIPTION
The front fog lamp relay is located in the Junction
Block (JB) on the driver side outboard end of the
instrument panel in the passenger compartment of
the vehicle. The front fog lamp relay is a conven-
tional International Standards Organization (ISO)
micro relay (Fig. 11). Relays conforming to the ISO
specifications have common physical dimensions, cur-
rent capacities, terminal patterns, and terminal func-
tions. The relay is contained within a small,
rectangular, molded plastic housing and is connected
to all of the required inputs and outputs by five inte-
gral male spade-type terminals that extend from the
bottom of the relay base.
The front fog lamp relay cannot be adjusted or
repaired and, if faulty or damaged, the unit must be
replaced.
OPERATION
The front fog lamp relay is an electromechanical
switch that uses a low current input from the Body
Control Module (BCM) to control a high current out-
put to the front fog lamps. 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 windings. 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 voltage spikes and
electromagnetic interference that can be generated as
the electromagnetic field of the relay coil collapses.
The front fog lamp relay terminals are connected
to the vehicle electrical system through a connector
receptacle in the Junction Block (JB). The inputs and
outputs of the front fog lamp relay include:
²Common Feed Terminal- The common feed
terminal (30) receives battery current at all times
from a fuse in the JB through a fused B(+) circuit.
²Coil Ground Terminal- The coil ground termi-
nal (85) is connected to a control output of the pre-
mium Body Control Module (BCM) through a front
fog lamp relay control circuit. The BCM controls
front fog lamp operation by controlling a ground path
through this circuit.
²Coil Battery Terminal- The coil battery ter-
minal (86) receives battery current at all times from
a fuse in the JB through a fused B(+) circuit.
²Normally Open Terminal- The normally open
terminal (87) is connected to the front fog lamps
through a front fog lamp relay output circuit and
provides battery current to the front fog lamps when-
ever the relay is energized.
²Normally Closed Terminal- The normally
closed terminal (87A) is not connected in this appli-
cation.
The front fog lamp relay can be diagnosed using
conventional diagnostic tools and methods.

HAZARD SWITCH
DESCRIPTION
The hazard switch is integral to the hazard switch
module, which is secured near the center of instru-
ment panel just above the radio (Fig. 21). Only the
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
module is connected to the vehicle electrical system
through a dedicated take out and connector of the
instrument panel wire harness. Within the hazard

switch module housing is the hazard switch circuitry
and an electronic circuit board with the integral com-
bination flasher circuitry. The electronic combination
flasher circuitry performs both the hazard flasher
and turn signal flasher functions.
The hazard switch module cannot be adjusted or
repaired and, if faulty or damaged, the unit must be
replaced.
OPERATION
The hazard switch button is slightly recessed in
the instrument panel when the switch is in the Off
position, and latches at a position that is flush with
the outer surface of the instrument panel when in
the On position. The hazard switch module produces
an audible clicking sound that emulates the sound of
a conventional flasher whenever the turn signals or
the hazard warning system are activated. The hazard
switch module receives battery current on a fused
B(+) circuit from a fuse in the Junction Block (JB) at
all times for operation of the hazard warning, and on
a fused ignition switch output (run) circuit from
another fuse in the JB whenever the ignition switch
is in the On position for operation of the turn signals.
The module receives a path to ground through a
splice block located in the instrument panel wire har-
ness 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. Inputs to
and outputs from the hazard switch module include:
²Panel Lamps Dimmer Input- A non-service-
able incandescent bulb soldered onto the hazard
switch module circuit board provides illumination of
the switch button when the exterior lighting is
turned On through an input received on the fusedpanel lamps dimmer switch signal circuit. However,
this bulb flashes on and off at full intensity whenever
the hazard switch button is in the On position,
regardless of the status of the exterior lighting.
²Hazard Switch Input- The combination
flasher circuitry of the hazard switch module receives
an internal ground input from the hazard switch to
request hazard flasher operation.
²Multi-Function Switch Input- The combina-
tion flasher circuitry of the hazard switch module
receives separate ground inputs from the turn signal
switch circuitry of the multi-function switch on right
and left turn switch sense circuits to request right or
left turn signal flasher operation.
²Body Control Module Input- The Body Con-
trol Module (BCM) can request hazard flasher opera-
tion by providing a ground path to the combination
flasher circuitry of the hazard switch module through
a hazard lamp control circuit.
²Turn Signal Output- The combination flasher
circuitry within the hazard switch module responds
to the flasher request inputs by energizing and
de-energizing two miniature relays on the module
circuit board. These relays control the switch output
through the right and left turn signal circuits. One
relay controls the right lamps, while the other con-
trols the left.
Because of active electronic elements within the
hazard switch module, it cannot be tested with con-
ventional automotive electrical test equipment. If the
hazard switch module is believed to be faulty, replace
the switch with a known good unit to confirm system
operation.

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.
