Electrical System
Add-On Electrical Equipment
Notice: Do not add anything electrical to your
vehicle unless you check with your dealer/retailer
first. 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, see Servicing
Your Airbag-Equipped Vehicle on page 1-74.
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 fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires
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.
