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, see
Servicing Your Air Bag-Equipped Vehicle on page 1-62.
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 fixed.
Power Windows and Other Power
Options
Circuit breakers in the fuse block protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem is fixed or
goes away.
5-89

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.
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: two
instrument panel fuse blocks and the engine
compartment fuse block.
There is a fuse puller located on the engine
compartment fuse block. It can be used to easily
remove fuses from the fuse block.The instrument panel fuse
blocks are located at each
end of the instrument
panel. To access
the fuses, open the fuse
panel door by pulling out.
To reinstall the door, insert the hooks at the front end
first, then push the door into the instrument panel
to secure it.
