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 air bag system. Before attempting
to add anything electrical to your vehicle, see
Servicing Your Air Bag-Equipped Vehicle on page 1-67.
Headlamp Wiring
The headlamp wiring is protected by different fuses
located in the underhood fuse block. An electrical
overload may cause the lamps to go off and remain that
way. If this happens, replace the right fuse with one
of the same kind and amperage.
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, be sure to get it fixed.

Power Windows and Other Power
Options
Circuit breakers in the floor console 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.
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.
Look at the silver-colored L-Band inside the fuse. If the
L-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 or use one of the spare fuses in the underhood
fuse and relay center. 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 right
amperage. Replace it as soon as you can.
There are two fuse blocks in your vehicle: the floor
console fuse block and the underhood fuse block.
