Windshield Wiper Blade Replacement
Windshield wiper blades should be inspected at least
twice a year for wear and cracking. See “Wiper Blade
Check” in the Index 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” in the
Index. Here’s how to remove the Shepherd’s Hook type.
To replace the windshield wiper blade assembly:
1. Lift the wiper arm and turn the blade until it is facing
away from the windshield.
2. Push the release lever and slide the wiper assembly
toward the driver’s side of the vehicle.
3. Install a new blade by reversing Steps 1 and 2.
