Windshield wiper blades should be inspected for wear or cracking. See Owner Checks and Services .

It is a good idea to clean or replace the wiper blade assembly on a regular basis or when worn. For proper windshield wiper blade length and type, see Maintenance Replacement Parts .

To replace the wiper blade assembly, do the following:

  1. Turn the ignition to ON with the engine off.
  2. Turn on the windshield wipers and turn them off again when the wipers are in the out-wipe position. The driver's side blade will be straight up and down on the windshield.
  3. Pull the windshield wiper assembly away from the windshield.

  5. Lift the wiper blade assembly up so it is in a T-shaped position. You should be able to see a tab.
  6. Squeeze the tab together and pull the wiper blade assembly down far enough to release it from the J-hooked end of the wiper arm. Slide the assembly away from the arm.
  7. Allowing the wiper blade arm to touch the windshield when no wiper blade is installed could damage the windshield. Any damage that occurs would not be covered by your warranty. Do not allow the wiper blade arm to touch the windshield.

  8. Replace the blade with a new one.

  10. Reinstall the wiper blade assembly by sliding it over the wiper arm to engage the J-hooked end. Pull up on the assembly to lock it into place.
  11. Repeat the steps for the other wiper.
