Fuses and Circuit
Breakers
The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses and circuit
breakers. This greatly reduces the
chance of damage caused by
electrical problems.
{Danger
Fuses and circuit breakers are
marked with their ampere rating.
Do not exceed the
specified amperage rating when
replacing fuses and circuit
breakers. Use of an oversized
fuse or circuit breaker can result
in a vehicle fire. You and others
could be seriously injured or
killed.
To check a fuse, look at the
silver-colored band inside the fuse.
If the band is broken or melted,
replace the fuse. Be sure to replace
a bad fuse with a new one of the
identical size and rating. Fuses of the same amperage can
be temporarily borrowed from
another fuse location, if a fuse goes
out. Replace the fuse as soon as
possible.
There is a fuse puller in the engine
compartment fuse block. See
Engine Compartment Fuse Block
0
307. It can be used to easily
remove fuses from the fuse block.
To identify and check fuses, circuit
breakers, and relays see Engine
Compartment Fuse Block 0307 or
Instrument Panel Fuse Block 0310
and
Rear Compartment Fuse Block
0 312.
Engine Compartment

component on the vehicle may
damage it. Always keep the
covers on any electrical
component.
