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.
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.
To identify and check fuses, circuit
breakers, and relays, seeEngine
Compartment Fuse Block 0269,
Instrument Panel Fuse Block 0272, and
Rear Compartment Fuse Block 0274.
Engine Compartment Fuse
Block
