Remove old wiper
Install New Blade
When the wipers no longer clean adequately, the wiper blades may be worn or cracked requiring replacement.
  1. Pull the top end of the rubber inward until the rubber blade is free of the end slot, and you can see the replacement hole.
  2. Pull the rubber blade out of the replacement hole.
  3. To install a new rubber, insert the end with small protrusions into the replacement hole, and work the rubber along the slot in the blade frame.
  4. Once all of the rubber is in the frame slot, allow it to expand and fill in the end.

Be carefull not to scratch the glass surface with the wiper frame.
