FAQs

Does this wiper arm include a blade?

No, the V10-9921 is the wiper arm and cap assembly; the wiper blade must be purchased separately.

Is this a genuine original equipment part?

VAICO is a reputable aftermarket manufacturer that builds parts to meet or exceed original equipment standards.

How do I know if this is compatible with my car?

Check your current rear wiper arm for one of the compatible OE numbers: 5K6955435, 5M0955427A, 5M0955707A, or 8K9955407.

Can I install this without professional tools?

Yes, standard socket wrenches are usually the only tools required for a basic replacement.

What is the purpose of the included cap?

The cap protects the mounting nut and bolt assembly from corrosion, moisture, and debris while providing a finished, clean look.

Troubleshooting

Wiper arm does not sit flush against the glass

Verify the mounting nut is fully tightened and the arm is properly seated on the splined shaft.

Arm vibrates or chatters during operation

Ensure the wiper blade is correctly installed and that the wiper arm spring has proper tension.

Pros and Cons

Pros

  • Precise fitment reduces installation difficulty
  • Includes essential cap for aesthetic completion
  • Meets or exceeds original equipment quality standards
  • Restores rear visibility for safer driving in rain or snow

Cons

  • Requires proper OE part number matching to avoid fitment errors
  • Wiper blade usually sold separately
  • Limited to rear window application only

Setup, Compatibility & Care

Before installation, ensure your vehicle is parked on level ground and the ignition is off. Remove the old arm by lifting the protective cap and loosening the mounting nut, typically requiring a socket wrench. Once removed, ensure the mounting shaft is free of debris before sliding the new VAICO V10-9921 into place. Tighten the nut securely, then snap the provided cap into position to shield the hardware from moisture and grime. To extend the life of the wiper arm, periodically clean the arm and pivot point with a mild automotive cleaner to prevent mineral build-up, and replace your wiper blades at the first sign of rubber degradation to prevent unnecessary stress on the arm's spring.
