FAQs

Is this a universal fit wiper?

No, this is a vehicle-specific part. Always verify your vehicle compatibility using your registration or make and model details.

How long is this wiper blade?

This Bosch Aerotwin A401H blade measures 16 inches (approximately 400mm).

Can I use this on my front windshield?

No, this blade is specifically designed for placement on the rear vehicle window.

What makes the Aerotwin quiet?

The quiet operation is achieved through a combination of the soft, flexible rubber spine and the low-friction graphite coating.

How often should I replace this wiper?

It is generally recommended to replace wiper blades every 6 to 12 months, or sooner if you notice streaking or reduced visibility.

Troubleshooting

Wiper is streaking across the window

Clean the rubber edge with a damp cloth to remove debris or check if the glass has a film of wax that needs removal.

Blade makes a chattering noise

Ensure the blade is seated correctly on the arm and verify that the rear wiper arm spring still maintains adequate tension.

Pros and Cons

Pros

  • Extremely quiet operation during wiping cycles
  • Superior streak-free performance due to double micro edge
  • Robust construction offers long service life
  • Aerodynamic profile reduces wind lift

Cons

  • Specific to rear windshield applications
  • Requires verification of vehicle-specific attachment type
  • Non-universal fitment necessitates use of fitment tools

Setup, Compatibility & Care

Before installation, use the vehicle make and model search tool to confirm that the A401H is the correct part number for your specific rear wiper arm. To install, gently lift the wiper arm away from the glass, release the locking mechanism on the existing blade, and slide the old unit off. Snap the Bosch Aerotwin blade into place until you hear an audible click. To extend the life of your new blade, keep the glass clean of heavy wax or oil buildup and wipe the rubber element with a damp cloth occasionally to remove accumulated dirt or grime.
