able ash receiver/cigar lighter lamp is secured by an
integral mount to the outside of the cigar lighter halo
ring. A single lamp serves to illuminate both the
translucent halo ring and the ash receiver.

• Cargo/Dome Lamp - Several cargo/dome lamp

units located overhead in both the front and rear of
the vehicle interior are standard equipment. These
lamps feature a single incandescent bulb. An optional
version of these lamps includes an integral three-po-
sition switch that protrudes through the lamp lens.

• Cargo Lamp Switch - Toggle-type remote

cargo lamp switches located in the accessory switch
bezel in the center of the instrument panel, on the
back side of the cargo compartment bulkhead panel,
and on the rear cargo door pillar are an available
option on all van models. The instrument panel
switch has two Light-Emitting Diode (LED) units,

one for illumination and a second that provides an
indication. The switches mounted in the cargo com-
partment also have two LED units, but only the indi-
cation LED unit is functional in this application.

• Dome/Reading Lamp - An optional equipment

dome/reading lamp unit is located in the windshield
header area between the driver and passenger sun
visors. This lamp features two incandescent bulbs,
one dome lamp bulb and a second, dedicated reading
lamp bulb. An integral four-position switch protrudes
through the lamp lens.

• Dome Lamp/Intrusion Sensor - An optional

equipment

dome

lamp/intrusion

sensor

unit

located overhead in the vehicle interior. This lamp
features four incandescent bulbs, two for dome lamps
and two for dedicated right and left reading lamps.
This lamp has two integral three-position switches,
one to control interior lamp operation and one to con-
trol reading lamp operation. This lamp also houses
three intrusion sensors that are part of an optional
vehicle theft security system.

• Door Jamb Switch - A door jamb switch for

each front door is standard equipment on all models.
A door jamb switch for each sliding side door and the

LAMPS/LIGHTING - INTERIOR

right rear door is standard equipment on wagon mod-
els. The sliding and rear door jamb switches are not
available for van models.

• Entry/Exit Lamp - An entry/exit lamp to illu-

minate each front and sliding side door step well is
optional equipment on wagon models.

• Time Delay Relay - Vehicles equipped with the

optional remote cargo lamp switches also have a time
delay relay located in the electrical center within the
driver side front seat riser.

Hard wired circuitry connects the interior lighting

system components to the electrical system of the
vehicle. These hard wired circuits are integral to sev-
eral wire harnesses, which are routed throughout the
vehicle and retained by many different methods.
These circuits may be connected to each other, to the
vehicle electrical system and to the interior lighting
system components through the use of a combination
of soldered splices, splice block connectors, and many
different types of wire harness terminal connectors
and insulators. Refer to the appropriate wiring infor-
mation. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures,
further details on wire harness routing and reten-
tion, as well as pin-out and location views for the
various wire harness connectors, splices and grounds.

OPERATION

The interior lighting systems can be divided into

two general classifications based upon the circuit
that controls their operation: The interior lighting
circuit, or the exterior lighting circuit. The hard
wired circuits and components of the interior lighting
systems may be diagnosed and tested using conven-
tional diagnostic tools and procedures.

INTERIOR LIGHTING CIRCUIT

Depending upon the vehicle model (van or wagon)

and the selected vehicle options the interior lighting
circuit may include dome/cargo lamps located over-
head in the front and rear of the vehicle, a dome/
reading lamp located in the header area above the
windshield between the sun visors, and entry/exit
lamps located in the front and sliding side door step
wells.

WAGON MODELS

In all wagon models, the lamps in the interior

lighting circuit are provided with battery current at
all times by a fuse in the fuse block beneath the
steering column. The front, side, and rear door jamb
switches control a ground path for each of these
lamps, except for the optional reading lamp. If the
lamp has an optional integral switch, that switch has
three separate positions. The first position provides a
ground path independent of the door jamb switches
to turn the lamp On. The second, or center position
allows the door jamb switches to control the lamp.

The third position segregates that lamp from the
door jamb switch input, turning the lamp Off. In the
case of the optional dome/reading lamp, the integral
lamp switch has a fourth position which will illumi-
nate only the reading lamp bulb.

VAN MODELS

Unless a van model is equipped with an optional

remote cargo lamp switch, all of the lamps in the
interior lighting circuit operate the same way as the
wagon models except that there are only two door
jamb switches, one for each front door. If the vehicle
is equipped with an optional remote cargo lamp
switch, the lamps in the rear of the vehicle on the
interior lighting circuit are provided with battery
current by the time delay relay. The time delay relay
is a smart relay containing active electronic elements
that comprise an electronic timer logic circuit. When
the remote cargo lamp switches provide the proper
input to the time delay relay, the relay logic responds
by energizing the relay control coil. The energized
relay control coil provides battery current to all of
the lamps on the rear interior lighting circuit and to
the indicator Light-Emitting Diode (LED) units in
the remote cargo switches causing each to illuminate.
If a remote cargo lamp switch remains On for more
than about fifteen minutes, the time delay relay will
then automatically de-energize the rear interior
lighting circuits until the remote cargo lamp switch
is cycled Off and then back On.

EXTERIOR LIGHTING CIRCUIT

The exterior lighting circuit provides battery cur-

rent to the optional ash receiver/cigar lighter lamp
and to the illumination Light-Emitting Diode (LED)
unit within the remote cargo lamp switch in the
instrument panel accessory switch bezel whenever
the exterior lamps are turned On.

ASH RECEIVER / CIGAR
LIGHTER LAMP UNIT

REMOVAL

An ash receiver/cigar lighter lamp unit is optional

equipment on this model (Fig. 1). The bulb and bulb
holder are secured by an integral mount to the out-
side of the cigar lighter halo ring, and serves to illu-
minate both the translucent halo ring and the ash
receiver. A small lens that is snap-fit into the inboard
side of the ash receiver bin allows light from the
lamp on the halo ring to also illuminate the ash
receiver. The ash receiver/cigar lighter lamp is ser-
viced only as a unit with the ash receiver housing
and cigar lighter receptacle. If the lamp is faulty or
damaged, the entire ash receiver housing and cigar
lighter receptacle unit must be replaced. (Refer to 23
- BODY/INSTRUMENT PANEL/ASH RECEIVER -
