Windshield Wiper Blade
Replacement
Windshield wiper blades should be inspected for
wear or cracking. See Scheduled Maintenance
on page 523.
Replacement blades come in different types and
are removed in different ways. To replace the
wiper blade assembly, do the following:
1. Pull the windshield wiper arm connector away
from the windshield.
2. Squeeze the grooved areas on each side of
the blade, and rotate the blade assembly
away from the arm connector.
3. Install the new blade onto the arm connector
and make sure the grooved areas are fully set
in the locked position.
For the proper type and size, see Normal
Maintenance Replacement Parts on page 535.
