Electrical System
Add-On Electrical Equipment
Notice:Don’t add anything electrical to your
vehicle unless you check with your dealer rst. Some
electrical equipment can damage your vehicle and
the damage wouldn’t be covered by your warranty.
Some add-on electrical equipment can keep other
components from working as they should.
Your vehicle has an air bag system. Before attempting
to add anything electrical to your vehicle, seeServicing
Your Air Bag-Equipped Vehicle on page 1-60.
Headlamp Wiring
The headlamp wiring is protected by fuses, one for
each headlamp, in the fuse block. An electrical overload
will cause the lamps to turn off. If this happens, have
your headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due
to heavy snow, etc., the wiper will stop until the
motor cools. If the overload is caused by some electrical
problem and not snow, etc., be sure to get it xed.
Power Windows and Other Power
Options
Fuses in the fuse block protect the power windows
and other power accessories. When the current load is
too heavy, the fuse opens protecting the circuit until
the problem is xed or goes away.
5-87

Fuses
The wiring circuits in your vehicle are protected from
short circuits by fuses and fusible thermal links in
the wiring itself.
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 a 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.There are three fuse blocks in your vehicle: one in the
center of the instrument panel, one in the engine
compartment and one in the trunk.
There is a fuse puller located on the instrument panel
fuse block. It can be used to easily remove fuses
from the fuse block.
The instrument panel fuse blocks is located at on the
lower front side of the console, on the passenger side of
the vehicle. To access the fuses, open the fuse panel
door by pulling out.
To reinstall the door, insert the hooks at the front end
rst, then push the door into the center console panel to
secure it.
