Electrical System

Add-On Electrical Equipment

Notice: Do not add anything electrical to your
vehicle unless you check with your dealer
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 84.

Headlamp Wiring

The headlamp circuit is protected by individual
fuses in the underhood fuse block. An electrical
overload will cause the fuse to blow. If this
happens, have your headlamp system checked
right away.

Windshield Wiper Fuses

The windshield wiper motor is protected by 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 instrument panel fuse
block protects 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.

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.
