Electrical System

Add-On Electrical Equipment

Notice: Don't add anything electrical to your vehicle
unless you check with your dealer first. 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 airbag system. Before attempting to
add anything electrical to your vehicle, see Servicing
Your Airbag-Equipped Vehicle on page 1-70.

Headlamp Wiring

The headlamp wiring is protected by fuses. Should your
headlamps fail to function, have your headlamp system
checked right away.

Windshield Wiper Fuses

The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow or ice, the wiper will stop until the motor cools.
If the overload is caused by some electrical problem,
have it fixed.

Power Windows and Other
Power Options
Fuses in the fuse block protect the power windows.
When the current load is too heavy, the fuse opens
protecting the circuit until the problem is fixed.

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 damage 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 do not 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.
There are two fuse blocks in your vehicle: the floor
console fuse block and the engine compartment
fuse block.
