Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer/retailer
rst. Some electrical equipment can damage
your vehicle and the damage would not be covered
by your warranty. Some add-on electrical equipment
can keep other components from working as they
should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before attempting
to add anything electrical to your vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-70.
Windshield Wiper Fuses
The windshield wiper motor is protected by a 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,
have it xed.
Power Windows and Other
Power Options
Circuit breakers protect the power windows and other
power accessories. If the current load is too heavy,
the circuit breaker opens and then closes after a cool
down period, protecting the circuit until the problem
is xed or goes away.
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 res 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 don’t 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.
