A list of all production options and special equipment.

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 link\
s in the wiring
itself. This greatly reduces the chance of fires caused by electrical problems.
See “Fuses and Circuit Breakers” in the Index for more i\
nformation.

Downloaded from www.Manualslib.com manuals search engine 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 and 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 prob\
lem 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 b\
reaker opens
and closes, protecting the circuit until the problem is fixed
or goes away.
Trailer Wiring Harness
The optional seven-wire trailer wiring harness is protected by \
an in-line fuse
in the battery feed wire. This fuse is near the junction bloc\
k. See “Trailer
Wiring Harness” in the Index.
Fuse Block
K3629
The fuse block is under the instrument panel on the driver’\
s side. You can
remove the cover with
a screwdriver and then remove fuses with a fuse
extractor. To remove fuses
if you don’t have one, hold the end of the fuse
between your thumb and index finger and pull straight out.

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
