pushing them slightly toward the front lamp unit
housing, outward to each side of the bulb base, then
pivot the retainers off of the bulb base.
(5) Remove the fog lamp bulb from the integral
bulb holder on the front lamp unit reflector.
INSTALLATION
(1) Position the fog lamp bulb into the integral
bulb holder on the front lamp unit reflector. Be cer-tain that the lugs on the bulb base are engaged in
the recesses of the bulb holder (Fig. 14).
(2) Engage the two fog lamp bulb retainers by piv-
oting them over the bulb base, pressing them slightly
toward the front lamp unit housing, then inward on
each side of the bulb base.
(3) Reconnect the front lamp unit wire harness
connector to the fog lamp bulb base.
(4) Position the front lamp unit rear cover onto the
lamp housing and engage the retainers over each
side of the cover to secure it (Fig. 13).

FOG LAMP RELAY
REMOVAL
Fog lamps are optional equipment on this model.
On vehicles equipped with fog lamps, a fog lamp
relay is located in a dedicated connector of the vehi-
cle wire harness. This connector is snapped into an
opening in a stamped sheet metal bracket which is
secured with screws within the driver side front seat
riser just beneath the seat riser cover panel.
WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental restraint system before attempting any
steering wheel, steering column, airbag, seat belt
tensioner, or instrument panel component diagno-
sis or service. Disconnect and isolate the battery
negative (ground) cable, then wait two minutes for
the system capacitor to discharge before perform-
ing further diagnosis or service. This is the only
sure way to disable the supplemental restraint sys-
tem. Failure to take the proper precautions could
result in accidental airbag deployment.
(1) Disconnect and isolate the battery negative
cable.
(2) Move the driver side front seat to its most for-
ward position for easiest access to the seat riser
cover panel (Fig. 15).
