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 1-55.
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 neaaiamp system cneckea
right away.
Windshield Wiper Fuses
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, have it fixed.
Power Windows and Other Power
Options
Circuit breakers in the rear 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.
5-91

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 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 you
replace a bad fuse with a new one of the identical
size and rating.
The MaxiFuses are located in
two fuse blocks, one in
the engine compartment and the other under the
rear seat. If a MaxiFuse should blow, have your vehicle
serviced by your dealer immediately.
Removing Fuses
You will find a fuse puller attached in both of the fuse
blocks. Snap the wide end of the fuse puller on
to
the fuse, at the side indentations holding the puller and
pull the fuse
out.
Engine Compartment Fuse Block
The engine compartment
fuse block is located in the
front
of the engine
compartment on the
passenger’s side. Lift the
cover
to gain access.
Fuse
22 or 23 can be moved to the outer position to
enable the accessory power outlet or cigarette lighter
when the ignition is not on. See your dealer for
additional assistance,
if needed.
