Fuse Block: Description and Operation
Fuse Block 2
FUSE BLOCK #2
An electrical fuse block is concealed under the driver side front seat The fuse block serves to distribute electrical current to many of the electrical
systems in the vehicle. The fuse block houses blade- type mini fuses, blade-type automatic resetting circuit breakers and International Standards
Organization relays. Additional provisions are available in the fuse block for additional fuses and ISO relays.
The molded plastic fuse block housing has an integral mounting bracket that is secured with screws to the seat base. The driver side seat base also has
a snap-fit fuse access panel that can be removed for service of the fuses and the relays. A finger recess is molded into one end for easy removal. A fuse
layout map is molded onto the back side of the panel to ensure proper fuse identification.
The fuse block is integral to the body wire harness. If any internal circuit or the fuse block housing is faulty or damaged, the entire fuse block and
body wire harness unit must be replaced.
All of the circuits entering and leaving the fuse block do so through the body wire harness. Internal connection of all of the fuse block circuits is
accomplished by an intricate combination of hard wiring and bus bars.
