Steps

  1. Lift the wiper arm away from the windshield: Pull it straight up until it locks in place pointing away from the glass.
  2. Press the release tab: Most wipers have a small plastic tab where the blade meets the arm. Press it and slide the old blade down and off.
  3. Slide on the new blade: Match the connector type from your old blade. Slide it up the arm until you hear a click.
  4. Lower the wiper gently: Hold the arm and ease it back to the windshield — don't let it slap against the glass.
  5. Repeat on the other blade: Don't forget the rear wiper if your vehicle has one.
  6. Test: Spray washer fluid and run the wipers a couple of cycles to verify a clean sweep.

Safety Notes

  • Don't let the bare wiper arm snap against the windshield — it can crack the glass
