The headlamp 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 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 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 and other
power accessories. When the current load is too heavy, the cir\
cuit breaker
opens and closes, protecting the circuit until the problem is fixed.
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 block in the
front, driver’s side fender. See “Trailer Wiring Harness” in the
Features &
Controls section.
Fuse B/ock
The fuse block is in
the instrument panel
on the driver’s side.
Remove the cover by
turning the fastener
counterclockwise.
Then you can remove
fuses with a fuse
extractor. Extra fuses
are provided in the
cover.

correct fuse.
Spare fuses are provided, however 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.
To reinstall the fuse panel cover, push in and turn the fastener clockwise.
