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.
This greatly reduces the chance of res
caused by electrical problems.
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 located on the
driver’s side edge of
the instrument panel.
Pull off the cover to
access the fuse block.
To remove fuses if you don’t have a fuse extractor,
hold the end of the fuse between your thumb
and index nger and pull straight out.
You may have spare fuses located behind the
fuse block access door. These can be used
to replace a bad fuse. However, make sure it is
of the correct amperage.
