NOTE: When removing or installing the IOD fuse, it
is important that the ignition switch be in the Off
position. Failure to place the ignition switch in the
Off position can cause the radio display to become
scrambled when the IOD fuse is installed. Remov-
ing and installing the IOD fuse again with the igni-
tion switch in the Off position will usually correct
the scrambled radio display condition.
REMOVAL
(1) Turn the ignition switch to the Off position.
(2) Remove the fuse access panel by unsnapping it
from the left outboard end of the instrument panel.
(3) Grasp the upper and lower tabs of the IOD
fuse holder unit in fuse cavity 12 of the JB between
the thumb and forefinger and pull the unit firmly
outward.
(4) Install the fuse access panel by snapping it
onto the left outboard end of the instrument panel.
INSTALLATION

RELAY AND FUSE BLOCK
The relay and fuse block is serviced as a unit with
the instrument panel wire harness. If any internal
circuit of the relay and fuse block or the relay and
fuse block housing is faulty or damaged, the entire
instrument panel wire harness unit must be
replaced.
