6-61 Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the underhood electrical center. 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
system 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,
have it fixed.
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 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
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.
Instrument Panel Fuse Block
Some fuses are located
in a fuse block on the
passenger's side of the
instrument panel. Pull off
the cover labeled FUSES to
expose the fuses.
