Fuses, Fuse Links and Circuit
Breakers
*
[ER00400(B FM)01/96]
Fuses, circuit breakers and fuse links protect
your vehicle's electrical system from overloading.
If electrical parts in your vehicle are not
working, the system may have been overloaded
and blown a fuse or tripped a circuit breaker.
Before you replace or repair any electrical parts,
check the appropriate fuses or circuit breakers.
*
[ER00450( ALL)01/96]
The following charts tell you which fuses or
circuit breakers protect each electrical part of
your vehicle. If a fuse blows or a circuit breaker
opens a circuit, all the parts of your vehicle that
use that circuit will not work.
[ER00500( M)01/96]
Selected circuits, such as headlamps and
windshield wipers, are protected with circuit
breakers. A circuit breaker is designed to stop
current flow in case of a short-circuit or
overload. It will automatically restore current
flow after a few seconds, but will again interrupt
current if the overload or short-circuit continues.
This on-off cycle will continue as long as the
overload or short-circuit exists.
*
[ER00550( ALL)01/96]
Once you have determined which fuses or circuit
breakers to check, follow the procedures under
Checking and replacing fusesorChecking and
replacing circuit breakerslater in this chapter.

Checking and Replacing Fuses
*
[ER02300( ALL)01/96]
If you need to check a fuse, follow these steps:
[ER02350( M)01/96]
1. Remove the fuse panel cover by squeezing
together the cover release tabs as you apply
a slight pulling motion at the same time. The
underside of the cover contains five spare
fuses and a fuse pulling tool in case you
need to replace a blown fuse.
*
[ER02550( M)01/96]
The spare fuses for your vehicle are color
coded as follows: 10 amp Ð red, 15 amp Ð
light blue, 20 amp Ð natural, 30 amp Ð light
green.

[ER02600( ALL)01/96]
2. On the fuse panel cover, find the number of
the fuse you want to check. The diagram on
the cover tells you where to locate the fuse
on the panel.
*
[ER02650(B FM)01/96]
The underside of the cover also contains a
fuse pulling tool in case you need to replace
a blown fuse.
*
[ER02700( ALL)01/96]
3. Check the fuse to see if it is blown. Look
through the clear side of the fuse to see if
the metal wire inside is separated. If it is,
the fuse is blown and should be replaced.

4. Replace the fuse with one that has the right
amperage rating (see previous chart).
*
[ER02850( ALL)01/96]
RWARNING
Always replace a fuse with one that has
the specified amperage rating. Using a
fuse with a higher amperage rating can
cause severe wire damage and could start
a fire.
*
[ER02900( ALL)01/96]
5. Put the fuse panel cover back on.
*
[ER02950( ALL)01/96]
Even after you replace a fuse, it will continue to
blow if you do not find what caused the
overload. If the fuse continues to blow, have
your electrical system checked.
