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.

Headlights
The headlight wiring is protected by a circuit breaker in the \
light switch. An electrical overload will cause the lights to go on and
off, or in some cases to
remain
off. If this happens, have your headlight wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit breaker a\
nd a fuse. If
the motor overheats due to heavy snow, etc., the wiper will s\
top until the
motor cools. If the overload is caused by some electrical problem and not
snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows a\
nd 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.
Trailer Wiring Harness
The optional seven-wire trailer wiring I ;s is protected by an in-line fuse
in the battery feed wire. This fuse is near rhe junction bloc\
k. See “Trailer
Wiring Harness” in the “Features
& Controls’’ section.
Fuse Block
KO631
The fuse block is in the instrument panel on the driver’s side.

Downloaded from www.Manualslib.com manuals search engine Be sure to use the correct fuse. If you ever have a problem on the road and
don’t have a spare fuse, you can “borrow” one of the correct value. 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 of the value you need. Replace it
as soon as you can. See “Fuses and Circuit Breakers” in this section.
