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, be sure to get it fixed.
Power Windows and Other
Power Options
Circuit breakers 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.
Power and Heated Seat Circuit
Breakers
There is a circuit breaker located underneath the
driver's side front seat that controls the power
and heated seat functions.

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 fires 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.
