Electrical System
Add-On Electrical Equipment
Notice: Don’t add anything electrical to your
vehicle unless you check with your dealer first.
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 air bag system. Before attempting
to add anything electrical to your vehicle, see
Servicing Your Air Bag-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, etc., 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
A circuit breaker in the fuse panel protects the power
windows. When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit until
the problem is fixed.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible links. This greatly reduces the chance of
damage 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 to
replace a bad fuse with a new one of the identical
size and rating.
There are three fuse blocks in your vehicle: two
instrument panel fuse blocks and the engine
compartment fuse block.
There are four spare fuses located in the driver’s side
instrument panel end cap for your use.
Instrument Panel Fuse Blocks
There are two fuse panels for your vehicle. One is
located on the driver’s side of the instrument panel and
the other is located on the passenger’s side.
