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 96 .
Headlamp Wiring
The headlamp wiring is protected by four internal
fuses in the underhood fuse block. An electrical
overload will cause the lamps to go on and off, or
in some cases to remain off. If this happens, have
your headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an
internal fuse in the underhood fuse block. 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, be sure to
get it fixed.
The rear washer pump is controlled by a relay
located in the engine compartment, behind
the windshield washer fluid reservoir. The rear
wiper motor is protected by a fuse located in the
instrument panel fuse block.
Power Windows and Other Power
Options
Circuit breakers in the instrument panel 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 fixed.
