Power Windows and Other Power
Options
Circuit breakers in the 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.
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 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.
There are spare fuses provided in the engine
compartment fuse block. 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
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 two fuse blocks in your vehicle: the
instrument panel fuse block and the engine
compartment fuse block.
There is a fuse puller located on the engine
compartment fuse block. It can be used to easily
remove fuses from the fuse block.
