Add-On Electrical Equipment
Notice:Don’t add anything electrical to your
vehicle unless you check with your dealer rst.
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, seeServicing
Your Airbag-Equipped Vehicle on page 1-60.
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 xed.
Power Windows and Other Power
Options
Circuit breakers in the fuse panel protect the power
seats. When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit until the
problem is xed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by fuses. This greatly reduces the chance
of circuit overload and re caused by electrical
problems.
There are two fuse blocks — the underhood fuse block,
and the instrument panel fuse block.
To identify and check fuses and relays, refer to the
Fuse Usage Chart on the inside surface of the
fuse panel door.
