Windshield Wiper Fuses
The windshield wiper motor is
protected by a circuit breaker and a
fuse. If the motor overheats due
to heavy snow or ice, the wiper will
stop until the motor cools. If the
overload is caused by some
electrical problem, have it xed.
Power Windows and
Other Power Options
Circuit breakers in the fuse block
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 xed or goes away.
Fuses and Circuit
Breakers
The wiring circuits in the vehicle are
protected from short circuits by
fuses. This greatly reduces
the chance of circuit overload and
re caused by electrical problems.
There are two fuse blocks — the
underhood fuse block, and the
instrument panel fuse block.
To identify and check fuses and
relays, refer to the Fuse Usage
Chart on the inside surface of the
fuse panel door.
Instrument Panel Fuse
Block
The instrument panel fuse block is
located on the passenger side
of the lower console.
Pull the latch of the fuse box cover
straight back to access the fuses.
