Add-On Electrical
Equipment
Notice: Do not add anything
electrical to the vehicle unless you
check with your dealer/retailer
first. Some electrical equipment
can damage the vehicle and the
damage would not be covered by
the vehicle's warranty. Some
add-on electrical equipment can
keep other components from
working as they should.
Add-on equipment can drain the
vehicle's battery, even if the vehicle
is not operating.
The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see
Servicing Your Airbag-Equipped
Vehicle on page 1-57.

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 fixed.
Power Windows and
Other Power Options
Circuit breakers in the 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 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 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.
Fuses of the same amperage can
be temporarily borrowed from
another fuse location, if a fuse goes
out. Replace the fuse as soon as
you can.
