Quick reference

Best aftermarket replacements

For your 2021 Tesla Model S, several premium aftermarket wiper blades offer excellent performance and durability:

• Bosch ICON: (Premium) Known for their beam blade technology, providing consistent pressure for a clear wipe. These are a popular choice for their all-weather performance and long lifespan.
• Rain-X Latitude: (Premium) Feature a reputable water-repellent coating that helps shed water off your windshield, improving visibility in wet conditions. Their beam blade design ensures even pressure.
• Trico Force: (Mid-Premium) Designed for robust performance, Trico Force blades often include a spoiler to help with aerodynamics at higher speeds, preventing lift-off and ensuring good contact with the windshield.
• Michelin Stealth: (Mid-Range) These blades combine the advantages of both traditional and beam blades, offering a hybrid design for effective wiping and durability.
• PIAA Si-Tech: (Premium) PIAA blades utilize silicone rubber, which can last longer and provide a smoother, quieter wipe. They also help water bead up on the windshield, similar to a water-repellent coating.

Attachment style

The 2021 Tesla Model S utilizes a push-button attachment style for its wiper blades. This unique design requires a specific type of wiper blade that can be easily clicked into place. While many aftermarket blades come with multiple adapters, ensure the one you choose is compatible with the push-button mechanism.

How to install

Replacing the wiper blades on your 2021 Tesla Model S is a straightforward process:

1. Lift the wiper arm: Carefully pull the wiper arm away from the windshield until it locks into the upright position. Be gentle to avoid damaging the arm or the windshield.
2. Remove the old blade: Locate the small tab or button on the wiper blade where it connects to the wiper arm. Press this tab and slide the old blade off the arm. You might need to wiggle it slightly to release it.
3. Attach the new blade: Align the new wiper blade with the wiper arm's attachment point. Ensure it's correctly oriented for the push-button mechanism. Slide the new blade onto the arm until it clicks securely into place.
4. Gently lower the arm: Carefully return the wiper arm to its resting position on the windshield.
5. Test the wipers: Turn on your wipers for a few cycles to ensure they are properly installed and functioning correctly.

Note: If you encounter any difficulty or if your aftermarket blades come with specific instructions for a "push-button" attachment, always refer to those instructions first.

When to replace

Wiper blades are crucial for safe driving visibility and should be replaced regularly. Here are some signs it's time for new blades:

• Timeframe: As a general rule, replace your wiper blades every 6 to 12 months, even if they appear to be working fine. The rubber can degrade over time due to exposure to UV light, extreme temperatures, and environmental contaminants.
• Streaking: If your wipers leave streaks across your windshield, it's a sign that the rubber is worn down or hardened. This can significantly reduce visibility, especially in heavy rain.
• Chattering or skipping: When wipers skip or make a chattering noise as they move across the windshield, it indicates that the blade is not making consistent contact. This is often due to a hardened or torn rubber element.
• Squeaking: A persistent squeaking sound can also indicate worn-out blades or an improper angle, both of which necessitate replacement.
• Visible damage: Regularly inspect your wiper blades for any visible signs of damage, such as cracks, tears, or missing pieces of rubber. If you see any of these, replace them immediately.
