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 ªServicing
Your Air Bag
-Equipped Vehicleº in the Index.
Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker. 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 system checked
right away.
Windshield Wipers
The windshield wiper motor is protected by an internal
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, be sure to have it fixed.
Power Windows and Other
Power Accessories
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 fixed or
goes away.
Maxifuse/Relay Center
To check the fuses in this underhood fuse center, turn
the two knobs one
-quarter turn counterclockwise and
loosen the metal wing nut on the passenger side of the
cover. Then remove the cover. The inside of the cover
has a chart that explains the features and controls
governed by each fuse and relay.

Passenger's Side Fuse Block
Additional fuses are located in the relay center, on the
passenger's side, below the instrument panel. You must
remove the sound insulator on the right side of the
passenger footwell to replace these fuses.
Since the replacement of these fuses can be difficult,
we recommend that you see your dealer for
fuse replacement.
