Windshield Wiper
Blade Replacement
Windshield wiper blades should be inspected at least
twice a year for wear or cracking. See “Wiper Blade
Check” under Part B: Owner Checks and Services on
page 6-19 for more information.
Replacement blades come in different types and are
removed in different ways. For proper type and length,
see Normal Maintenance Replacement Parts on
page 5-101.
To replace the wiper blade assembly, do the following:
1. Position the wipers on the windshield in the
“mid” wipe position.
2. Lift the windshield wiper arm away from the
windshield. The windshield wiper does not have a
locking upright position feature.
3. Push the tab on the wiper blade assembly and pull
the assembly down enough to release it from the
U-hooked end of the wiper arm. Slide the assembly
away from the arm.
4. Replace the blade.
5. To reinstall the wiper blade assembly, slide it over
the wiper arm to engage the U-hooked end on the
wiper blade assembly. Pull up on the assembly
to lock it into place.
