Headlamp Wiring
The headlamp wiring is protected by fuses, one for
each headlamp, in the fuse block. An electrical overload
will cause the lamps to turn off. If this happens, have
your headlamp wiring checked right away.
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 xed.
Power Windows and Other
Power Options
The power window motors are protected by a circuit
breaker in the motor, and a fuse in the fuse panel. If the
motor overheats due to a heavy load the window will stop
until the motor cools. When the current load is too heavy
the fuse will open, protecting the circuit until the problem
is xed.
Fuses
The wiring circuits in your vehicle are protected from
short circuits by fuses and fusible thermal links in
the wiring itself.
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.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick a feature of your vehicle that
you can get along without — like the radio or cigarette
lighter — and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
There are three fuse blocks in your vehicle: one in
the center of the instrument panel, one in the engine
compartment and one in the trunk.
There is a fuse puller located on the instrument panel
fuse block. It can be used to easily remove fuses
from the fuse block.
