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.
This protects the circuit until the current load returns
to
normal or the problem is fixed.
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. This
Instrument Panel Fuse Block
The fuse block access door
is on the driver’s side edge
of the instrument panel. Pull
off the cover to access the
fuse block.
You can remove fuses with
a fuse extractor. The fuse
extractor is mounted to the
fuse block access door.
greatly reduces the chance of fires caused by electrical
problems. See “Fuses and Circuit Breakers” in the Index
for more information.
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 correct amperage.
Replace it as soon as you can.
To remove fuses if you don’t have a fuse extractor, hold
the end of the fuse between your thumb and index finger
and pull straight out.
You may have spare fuses attached to the inside of
the fuse block access door. These can be used to
replace a bad fuse. However, make sure that it is the
correct amperage.
