WINDSHIELD WIPER BLADES
Check the wiper blades at least
twice a year or when they seem
less effective. Substances such as
tree sap and some hot wax
treatments used by commercial car
washes reduce the effectiveness of
wiper blades.
Checking the wiper blades
If the wiper blades do not wipe
properly, clean both the windshield
and wiper blades using undiluted
windshield wiper solution or a mild
detergent. Rinse thoroughly with
clean water. To avoid damaging the
blades, do not use fuel, kerosene,
paint thinner or other solvents.
Changing the wiper blades
When replacing wiper blade
assemblies, always use a
Motorcraft part or equivalent. To
make replacing the wipers easy,
turn the ignition to ACC, then turn
the wipers on. When the wipers
reach the vertical position, turn
the ignition to LOCK.
To replace the wiper blades:

gallons used
Keep a record for at least one
month. This will provide an
accurate estimate of the vehicle's
fuel economy.
