have
your headlamp system checked right away.

heavy snow, etc., the wiper
will stop until the motor
cools. If tbe overload is .caused by some electrical
problem, be

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. 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.
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 some feature of
your vehicle that
you can get along without -- like the radio or cigarette
lighter -- and use its fuse, if it is the eomect amperage.
Replace it as soon as you can.
There are two fuse blocks in your vehicle: the driver’s
side and passenger’s side fuse blocks.
Driver’s Side Fuse Block
The driver’s side fuse block is to the left of the steering
wheel, under the instrument panel.
Snap off the cover to reveal the fuses. You’ll find a fuse
puller clipped to the inside of the cover. Place the wide
end of the fuse puller over the plastic end of the fuse.
Squeeze the ends over the fuse and pull it out.
Spare fuses are located in the slots labeled “Spare”
on
the following chart.
When finished, replace the cover by snapping it back
up
into place.
