Windshield Wiper Fuses
The windshield wiper motor is protected by a
circuit breaker and a fuse. If the motor overheats
due to heavy snow or ice, 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
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 xed.
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 res 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 do not
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 correct amperage. Replace it as soon as
you can.
Instrument Panel Fuse Block
The instrument panel fuse block is located under
the instrument panel on the passenger side of
the vehicle. Pull down on the cover to access the
fuse block.
