Fuse Block: Description and Operation
Fuse Block 1
FUSE BLOCK #1
An electrical fuse block is concealed under the driver side steering column. The fuse block serves to distribute electrical current to many of the
electrical systems in the vehicle. The fuse block contains blade- type mini fuses, relays and micro processors that enable automatic control of some of
the power distribution circuits throughout the vehicle.
The molded plastic fuse block housing has an integral mounting bracket that is secured with screws to the steering column. A finger recess is molded
into the cover for easy removal. A fuse layout map is molded onto the back side of the cover to ensure proper fuse identification.
The fuse block cannot be repaired, if the fuse block is faulty or damaged or if any internal circuit is faulty or damaged, the entire fuse block must be
replaced.
All of the circuits entering and leaving the fuse block do so through the instrument panel wire harness. Internal connection of all of the fuse block
circuits is accomplished by an intricate combination of hard wiring and bus bars. Internal relays and micro processors allow the vehicle electronics to
control some of the power distribution circuits throughout the vehicle. Refer to the Wiring section for complete circuit diagrams.
