Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected at least
twice a year for wear and cracking. See
″
Wiper
Blade Check” in Scheduled Maintenance on page 6-4.
Replacement blades come in different types and are
removed in different ways. To remove the type with a
release clip, do the following:
1. Lift the wiper arm until it locks into a vertical
position.
2. Press down on the blade assembly pivot locking
tab. Pull down on the blade assembly to release it
from the wiper arm hook.
3. The insert has two notches at one end that are
locked by bottom claws of the blade assembly.
At the notched end, pull the insert from the blade
assembly.
4. To install the new wiper insert, slide the notched
end last, into the end with two blade claws. Then
slide the insert all the way through the blade claws
at the opposite end.
5. Make sure that the notches are locked by the
bottom claws. Make sure that all other claws
are properly locked on both sides of the insert slot.
6. Put the blade assembly pivot in the wiper arm hook.
Pull it up until the pivot locking tab locks in the hook
slot.
7. Carefully lower the wiper arm and blade assembly
into the windshield.
