IOD FUSE (Continued)
(2) Remove the fuse access panel by unsnapping it
from the outboard end of the instrument panel.
(3) Grasp the outer tabs of the IOD fuse in cavity
# 19 of the Junction Block between the thumb and
forefinger and pull the unit firmly outward.
(4) Install the fuse access panel by snapping it
onto the outboard end of the instrument panel.
INSTALLATION
(1) Turn the ignition switch to the Off position.

JUNCTION BLOCK
DESCRIPTION
Fig. 4 Junction Block Location
1 - JUNCTION BLOCK/BCM
An electrical Junction Block (JB) is located in the
left endcap of the instrument panel (Fig. 4). The JB
combines the functions previously provided by a sep-
arate fuseblock module and relay center. It also
serves to simplify and centralize numerous electrical
components, as well as to distribute electrical current
to many of the accessory systems in the vehicle. It
eliminates the need for numerous splice connections
and serves in place of a bulkhead connector between
many of the engine compartment, instrument panel,
and body wire harnesses.
8W-97 POWER DISTRIBUTION
The JB is positioned on a mounting bracket up and
under the left instrument panel. It is secured by four
screws. The JB is concealed behind the left instru-
ment panel endcap. The left instrument panel endcap
is a snap-fit fuse access cover that conceals the JB
fuses. The left instrument panel endcap must be
removed to access components other than the fuses
in the JB.
OPERATION
All of the current entering and leaving the JB does
so through wire harnesses, which are connected to
the JB through integral connector receptacles molded
into the JB housing. The JB houses blade-type fuses,
blade-type automatic resetting circuit breakers, full
International Standards Organization (ISO) relays,
and ISO micro-relays. Internal connection of all the
JB circuits is accomplished by an intricate network of
hard wiring and bus bars. 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.
The fuses, circuit breakers, relays, and are avail-
able for service replacement. The JB unit cannot be
repaired and is only serviced as an assembly. If any
internal circuit or the JB housing is faulty or dam-
aged, the entire Junction Block assembly must be
replaced.
REMOVAL
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS,
BEFORE ATTEMPTING ANY STEERING WHEEL,
STEERING COLUMN, OR INSTRUMENT PANEL
COMPONENT DIAGNOSIS OR SERVICE. FAILURE
TO TAKE THE PROPER PRECAUTIONS COULD
RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND POSSIBLE PERSONAL INJURY.
The Junction Block and Body Control Module
(BCM) are attached to each other. After removal,
they can be separated. The Junction Block/BCM
assemblies are located on the driver's side of the
vehicle.
(1) Open hood and disconnect the negative battery
cable remote terminal from the remote battery post.
(2) Open the front driver's door and remove left
end cap.
(3) Remove two screws from lower instrument
panel cover (outside end). Pull rearward on lower
instrument panel cover releasing clips. Disconnect
decklid release switch wiring, cable to hood release,
and remove cover from vehicle.
