Do you need to replace your Tesla’s wiper blades? Here’s how to tell, and what to buy.

If your wipers are streaking, skipping, or squealing across the glass, the blades are worn, not the motor. It’s a five-minute fix once you have the right size.

What size to buy

Tesla’s own Model 3 wiper blade listing and Model Y wiper blade listing confirm the factory sizing: both cars use a 26-inch blade on the driver’s side. The passenger side differs by model — 19 inches on Model 3, 20 inches on Model Y. Buying the wrong passenger-side length is the most common mistake, since the two cars look similar but aren’t interchangeable there.

Why the connector matters more than the brand

Tesla uses Bosch-style wiper arm connectors, and most quality aftermarket blades — including Bosch ICON blades, which are the same design Tesla installs from the factory — include an adapter for it. The adapter size can vary by model year, so check that the box or listing explicitly lists Model 3 or Model Y compatibility rather than assuming any 26-inch blade will click into place.

How to swap them without a fight

Park the car, then go to Controls > Service > Wiper Service Mode in the touchscreen. This lifts the wipers away from the glass and, just as importantly, disables auto-wipe so the arm doesn’t swing into your hand mid-swap. From there, unclip the old blade from the hook-style arm, seat the new blade until it clicks, and confirm it’s locked by giving it a gentle tug before exiting service mode.

Plan on replacing blades roughly once a year, sooner if you park outside in full sun or after a hard freeze — UV exposure and ice both crack the rubber edge faster than mileage does.
