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 air bag system. Before attempting
to add anything electrical to your vehicle, see
Servicing Your Air Bag- Equipped Vehicle on page 1-83.
Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker in the floor console fuse block. An electrical
overload will cause the lamps to go on and off, or
in some cases to remain 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, 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 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 or use one o f 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 and relay
center.
