Periodically inspect the wiper blades and arms for wear or damage. Check the security of the fasteners. If the brushes are worn out, they must be replaced.
1. Raise the wiper arm, push in the retaining tab and remove the blade from the wiper arm.
2. Squeeze the mounting clips of the rubber insert and remove the insert.
3. Transfer the metal fasteners to the new rubber insert and install it on the brush.
4. Attach the brush to the wiper arm.
