About these Wiper Blades

The BOSCH 3-397-118-421 wiper blades clear rain and spray from your windshield or rear window. The rubber edge hardens and wears with sun and use, so blades should be replaced regularly to keep visibility clear.

Frequently asked questions

How often should I replace wiper blades?

Typically every six to twelve months, or sooner if they streak, chatter or leave unwiped areas. Heat, sun and ice shorten their life.

What are the signs of worn wiper blades?

Streaks or smears, chattering or skipping across the glass, unwiped areas, squeaking, or a rubber edge that is cracked, torn or hardened.

How do I choose the right size?

Front blades are often different lengths on the driver and passenger sides, and the connector type must match your wiper arms. Check the fitment information or measure your existing blades.

How do I make wiper blades last longer?

Keep the windshield clean, clear ice and snow before using the wipers, and avoid running them on a dry windshield.

How do I make sure this wiper blade fits my car?

Compare the part numbers listed on this page with the number on your old part or in your vehicle's parts catalog, and check the fitment information. If you are unsure, contact us with your VIN before ordering.
