6-61 Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links in the wiring itself. This
greatly reduces the chance of fires caused by electrical
problems. See ªFuses and Circuit Breakersº in the Index
for more information.
Look at the silver
-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
If you ever have a problem on the road and don't have a
spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as you can.Instrument Panel Fuse Block
The fuse block access door
is on the driver's side edge
of the instrument panel. Pull
off the cover to access the
fuse block.
You can remove fuses with
a fuse extractor. The fuse
extractor is mounted to the
fuse block access door.
To remove fuses, if you don't have a fuse extractor, hold
the end of the fuse between your thumb and index finger
and pull straight out.
You may have spare fuses attached to the inside of
the fuse block access door. These can be used to
replace a bad fuse. However, make sure that it is the
correct amperage.
