Windshield wiper blades should be inspected at least twice a year for wear or cracking. See "Wiper Blade Check" under Owner Checks and Services 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 replace the windshield wiper blades:

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

  4. Object Number: 811525  Size: B3
  5. Pull up the release clip, located at the connecting point of the blade and the arm. Then, pull the blade assembly down toward the glass to remove it from the wiper arm.
  6. Push the new wiper blade securely on the wiper arm until you hear the release clip "click" into place.
  7. Push the release clip, from Step 4, down to secure the wiper blade into place.

To replace the backglass mounted wiper blade, do the following:

  1. Turn the rear wiper off.
  2. Pull the wiper away from the backglass.
  3. Pull up the release clip, located at the connecting point of the blade and the arm. Then, pull the blade assembly down toward the glass to remove it from the wiper arm.
  4. Push the new wiper blade securely on the wiper arm until you hear the release clip "click" into place.
  5. Push the release clip, from Step 3, down to secure the wiper blade into place.
