Q: What should be inspected periodically for damage, loose components, and cracked or worn blade elements?
A: Inspect the windshield wiper and blade assembly regularly for damage, loose parts, and worn blade elements. Clean wiper blades with mild detergent to remove road film. Check and tighten any loose bolts or fasteners during inspection. Replace cracked, worn or ineffective wiper blades. For pre-1991 models, remove the old rubber blade by pulling it free from the end slot, then insert a new one into the replacement hole and slot it into the frame. For 1991 and later models, detach the old blade insert and replace it with a new one, securing it in place.
