Maintaining clear visibility is critical for the safety and autopilot functionality of your 2020 Tesla Model Y. Because the forward-facing cameras rely on a clean windshield to operate properly, keeping your wiper blades in top condition is an absolute must.

Here is the essential sizing and part information for your 2020 Tesla Model Y wiper blades:
| Position | Length (in) | Length (mm) | Attachment | OEM PN |
|---|---|---|---|---|

Note: The 2020 Tesla Model Y is not equipped with a rear wiper blade.
Best aftermarket replacements
If you prefer to upgrade from the factory blades, the aftermarket offers several premium beam-style blades that contour perfectly to the Model Y's aerodynamic windshield.
- Bosch ICON: (Premium price tier) The gold standard for beam blades. They offer exceptionally long life and reliable, streak-free performance in extreme weather.
- Rain-X Latitude: (Mid-to-high price tier) Excellent at repelling water, these blades treat your windshield with a water-beating coating as they wipe.
- Trico Force: (Mid price tier) Designed with a swept-wing spoiler to maximize downward aerodynamic pressure, making them highly effective at highway speeds.
- Michelin Stealth: (Mid price tier) A durable hybrid blade with a smart-flex design that provides a solid, uniform wipe across the glass.
- PIAA Si-Tech: (Premium price tier) Silicone-based blades that are highly resistant to UV breakdown and ozone, lasting much longer than standard rubber blades.
Attachment style
The 2020 Tesla Model Y uses a top push-button attachment style (often referred to as a narrow push-button or PTB). Unlike the older J-hook designs, the push-button mechanism allows the wiper blade to sit flush against the wiper arm for improved aerodynamics and a cleaner aesthetic. When buying aftermarket blades, ensure the package includes the correct push-button adapter.
How to install
Replacing the wiper blades on a Tesla Model Y requires an extra electronic step before you can physically swap them out.
- Enter Wiper Service Mode: On your Tesla touchscreen, navigate to Controls > Service > Wiper Service Mode and turn it ON. This will move the wipers up to the middle of the windshield so you can easily access them.
- Lift the Arm: Gently lift the wiper arm away from the windshield.
- Remove the Old Blade: Press the square push-button on the top of the wiper attachment joint and slide the blade down and away from the arm to release it.
- Install the New Blade: Slide the new wiper blade's adapter into the wiper arm slot until you hear and feel a distinct "click."
- Test and Reset: Gently lower the arm back to the glass. Go back to your touchscreen and turn off Wiper Service Mode to return the wipers to their resting position.
When to replace
For optimal safety and autopilot camera functionality, you should replace your wiper blades every 6–12 months. Environmental factors like intense UV exposure, road salt, and ice can degrade the rubber compound quickly. Watch for common signs of failure such as persistent streaking, missed patches, squeaking, or chattering across the windshield.
