The wiper blades and wiper arms should be inspected
periodically, not just when wiper performance problems
are experienced. This inspection should include the follow-
ing points:
Wear or uneven edges
Foreign material
Hardening or cracking
Deformation or fatigue
If a wiper blade or wiper arm is damaged, replace the
affected wiper arm or blade with a new unit. Do not
attempt to repair a wiper arm or blade that is damaged.

Do not allow the wiper arm to spring back against the
