1997 CHEVROLET BLAZER lock

Downloaded from www.Manualslib.com manuals search engine Headlamps
The headlamp wiring is protected by an internal circuit
breaker.
An electrical overload will cause the lamps to go
on and off, or in some cases to remain off. If this happens,
have your headlamp wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit breaker
and a fuse.
If the motor overheats due to heavy snow, etc., 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.
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 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 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.
Instrument Panel Fuse Block
The fuse block is at the
driver's end
of the
instrument panel.
Remove the cover by turning the fastener
counterclockwise. Extra fuses and the fuse extractor
are
provided in the cover. To reinstall the fuse panel cover,
push
in and turn the fastener clockwise.
