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 and loose parts. You can clean wiper blades with mild detergent to remove road film. Check and tighten any loose bolts or fasteners during inspection. Replace cracked or worn blades. Lift the arm assembly, pull the rubber blade inward until free, then remove and discard. Insert a new blade into the replacement hole, work it along the slot, and let it expand to fill the end.
