Q: What are some tips for maintaining and replacing windshield wiper blades on Ford Focus?
A: Wiper blades' efficiency can be affected by road film so clean them regularly using mild detergent. Inspect the wiper assembly for any damage and loose parts. Check bolts, nuts, and fasteners tightening them if necessary. Replace blades that are either cracked, worn out, or bent out of shape. To replace park wipers, switch off ignition, release pin, unhook arm, remove the blade, slide on a new blade and secure with spring lock.
