To remove and replace the wiper blade element:
1. The wiper blade element has two notches at one
end which are engaged by the bottom claw set of
the wiper blade. At the notched end of the wiper
blade, pull the wiper blade element from the wiper
blade assembly.
2. Replace the element by starting at the heel end of
the wiper blade, which is the end nearest to the base
of the wiper arm, and slide the wiper blade element,
notched end last, into the wiper blade claw sets.
3. Engage the last claw into the notched end of the
wiper blade element by squeezing the wiper blade
element at the notched area, and push the wiper
blade element so the claw ts into the notch.
4. Be sure the two wiper blade element notches are
engaged by the last claw set and all the other claws
are properly engaged in the slots of the wiper blade
element on both sides.A. Correct Installation

The vehicle has an airbag system. Before attempting to
add anything electrical to the vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-68.
Headlamp Wiring
The headlamp wiring system has four individual fuses. An
electrical overload will cause the lamps to go on and off,
or in some cases to remain off. If this happens, have the
headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
circuit breaker. If the wiper motor overheats due to
heavy snow, the wipers will stop until the motor cools
and will then restart.
A fuse powers the wiper motor. If the fuse blows, there
is an electrical problem. Be sure to 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 a combination of fuses and circuit
breakers. This greatly reduces the chance of res
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.
If you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of the vehicle that you
can get along without — like the radio or cigarette
lighter — and use its fuse, if it is the correct amperage.
Replace it as soon as you can.
Underhood Fuse Block
The underhood fuse block is located on the passenger
side of the engine compartment. Remove the fuse cover
and secondary service cover to access the fuse block.
Notice:Spilling liquid on any electrical components
on the vehicle may damage it. Always keep the
covers on any electrical component.
