Windshield wiper blades should be inspected for wear or cracking. See Scheduled Maintenance for more information.

Replacement blades come in different types and are removed in different ways. For proper type and length, see Maintenance Replacement Parts . Here's how to remove the wiper blades:

  1. Turn on the wipers to the LO wipe setting.
  2. Turn off the ignition while the wipers are at the outer positions of the wiper pattern. The blades are more accessible for removal/replacement while in this position.
  3. Pull the windshield wiper arm away from the windshield.

  6. Push the new wiper blade securely on the wiper arm until you hear the release clip click into place.
