Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your 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.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 88.
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 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 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.
