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.
DIAGNOSIS AND TESTING - FRONT FOG LAMP
RELAY
The front fog lamp relay (Fig. 12) is located in the
Junction Block (JB) under the driver side outboard
end of the instrument panel. 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.

no continuity between terminals 87 and 30. If OK, go
to Step 3. If not OK, replace the faulty relay.
(3) Resistance between terminals 85 and 86 (elec-
tromagnet) should be 75   8 ohms. If OK, go to Step
4. If not OK, replace the faulty relay.
(4) Connect a battery to terminals 85 and 86.
There should now be continuity between terminals

the cancel actuator when the steering wheel is
rotated to the left, but will unlatch the cancel actua-
tor as the steering wheel rotates to the right and
returns to center, which will cancel the turn signal
event and release the control stalk from the detent so
it returns to the neutral Off position. When a turn
signal is activated, the multi-function switch provides
a ground output on a right or left turn switch sense
circuit to the combination flasher circuitry within the
hazard switch, and the combination flasher flashes
the turn signal lamps.
RIGHT CONTROL STALK The right (wiper) con-
trol stalk of the multi-function switch operates as fol-
lows:
²Continuous Front Wipe Modes- The control
knob on the end of the multi-function switch right
(wiper) control stalk is rotated to an intermediate
detent that is one detent rearward (counterclockwise)
from the full forward (clockwise) detent to select the
low speed continuous front wiper mode, or to its full
forward (clockwise) detent to select the high speed
continuous front wiper mode. The multi-function
switch provides a resistor multiplexed output to the
Body Control Module (BCM) on a front wiper switch
mux circuit, and the BCM responds by energizing the
wiper on/off relay in the Power Distribution Center
(PDC) for the front low speed continuous wipe mode,
or the wiper on/off relay and the wiper high/low relay
in the PDC for the front high speed continuous wipe
mode as required.
²Continuous Rear Wipe Mode- The control
ring on the multi-function switch right (wiper) con-
trol stalk is rotated to the most forward (clockwise)
detent to select the continuous rear wiper mode. The
multi-function switch provides a battery current out-
put to the rear wiper motor on a rear wiper on driver
circuit to signal the rear wiper motor to operate in
the continuous wipe mode.
²Front Washer Mode- The right (wiper) control
stalk of the multi-function switch is pulled towards
the steering wheel to momentarily activate the
washer pump in the front washer mode. The washer
pump will continue to operate in the front washer
mode until the control stalk is released. The multi-
function switch provides a ground output on a
washer pump sense circuit, and battery current on a
washer pump driver circuit to energize the washer
pump in the front washer mode.
²Front Wiper Mist Mode- The right (wiper)
control stalk of the multi-function switch is pushed
towards the floor to momentarily activate the front
wiper motor in the mist mode. The front wiper motor
will continue to operate in the mist mode until the
control stalk is released. The multi-function switch
provides a resistor multiplexed output to the Body
Control Module (BCM) on a front wiper switch muxcircuit, and the BCM responds by energizing the
wiper on/off relay in the Power Distribution Center
(PDC) to operate the front wiper motor momentarily
at low speed to provide the front wiper mist mode.
²Intermittent Front Wipe Mode- The control
knob on the end of the multi-function switch right
(wiper) control stalk is rotated to one of five minor
intermediate detents to select the desired intermit-
tent front wipe delay interval. The control knob is
rotated rearward (counterclockwise) to increase the
delay, or forward (clockwise) to decrease the delay.
The multi-function switch provides a resistor multi-
plexed output to the Body Control Module (BCM) on
a front wiper switch mux circuit, and the BCM
responds by energizing the wiper on/off relay in the
Power Distribution Center (PDC) to operate the front
wiper motor at the selected delay intervals.
²Intermittent Rear Wipe Mode- The control
ring on the multi-function switch right (wiper) con-
trol stalk is rotated to the center detent to select the
intermittent rear wiper mode. The multi-function
switch provides a battery current output to the rear
wiper motor on a rear wiper intermittent driver cir-
cuit to signal the rear wiper motor to operate in the
intermittent wipe mode.
²Rear Washer Mode- The control ring on the
multi-function switch right (wiper) control stalk is
rotated to either the full forward (clockwise) or full
rearward (counterclockwise) momentary positions to
activate the washer pump in the rear washer mode.
The washer pump will continue to operate in the rear
washer mode until the control ring is released. The
multi-function switch provides a ground output on a
washer pump driver circuit, and battery current on a
washer pump sense circuit to energize the washer
pump in the rear washer mode.
