Wiper Blade Replacement
Windshield wiper blades should be inspected for wear or cracking. See Maintenance Schedule on page 11‑3 for more information on wiper blade inspection.
Replacement blades come in different types and are removed in different ways. To remove the wiper blade:
1. Pull the windshield wiper arm connector away from the windshield.
2. Squeeze the grooved areas on each side of the blade, and turn 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 Maintenance Replacement Parts on page 11‑15.
