Check each of the large f uses in
the under-hood f use box by
looking at the wire inside.
Removing these f uses requires a
Phillips-head screwdriver.
If something electrical in your
vehicle stops working, the first thing
youshouldcheckforisablownfuse.
Determine f rom the chart on pages
, and , or the diagram on
thefuseboxlidorthefuselabel,
which f use or f uses control that
component. Check those f uses f irst,
but check all the f uses bef ore
deciding that a blown f use is not the
cause. Replace any blown f uses and
check if the device works.
Turn the ignition switch to the
LOCK (0) position. Make sure the
headlights and all other
accessories are of f .
On the under-hood and passenger’s
side interior f use boxes, remove

If the replacement fuse of the
same rating blows in a short time,
there is probably a serious
electrical problem with your
vehicle. Leave the blown fuse in
that circuit, and have your vehicle
checked by a qualif ied technician.
If you cannot drive the vehicle
without f ixing the problem, and you
do not have a spare fuse, take a fuse
of the same rating or a lower rating
f rom one of the other circuits. Make
sureyoucandowithoutthatcircuit
temporarily (such as the accessory
power socket).
If you replace the blown f use with a
spare f use that has a lower rating, it
might blow out again. This does not
indicate that anything is wrong.
Replace the f use with one of the
correct rating as soon as you can.
Your vehicle has spare fuses on the
back of the under-hood f use box
cover. 6.

Replacing a f use with one that has a
higher rating greatly increases the
chances of damaging the electrical
system. If you do not have a
replacement f use with the proper rating
f or the circuit, install one with a lower
rating.
