1. Check the condition of the wiper blades. If they have cracks or other signs of damage, or if they stain the glass, replace them. Regardless of condition, replace your wiper blades annually to maintain good visibility
2. To remove the blade, move the wiper arm away from the glass until it locks into place. Rotate the brush 90°, press the lock at the base of the support
3. Slide the brush down the arm to release it from the support, and then remove the brush from the arm. Don't forget to check the tailgate glass wiper blade(s) as well (if available)
