Tesla Wiper Blades: Model 3/Y Sizes, Fitment and Replacement
Some links are affiliate links. As an Amazon Associate I earn from qualifying purchases. Check vehicle compatibility before buying. How recommendations work.
Model 3 and Model Y do not use the same passenger-side blade specification. Tesla's US manuals specify 26/19 inches for Model 3 and 26/20 inches for Model Y. Match the connector as well as the length before ordering: a blade that looks right in a search result may not attach to your arm.
This guide separates cleaning, choosing a replacement and fitting it. The shortlist is based on Tesla documentation and Bosch's application catalog, not a claim that we have personally tested every product on every model year.
Which wiper sizes does your Tesla need?
| Vehicle manual checked | Driver / passenger specification |
|---|---|
| Model 3, 2017–2023 | 26 / 19 in; 650 / 475 mm |
| Current Model 3, 2024+ | 26 / 19 in; 650 / 475 mm |
| Model Y, 2020–2024 | 26 / 20 in; 650 / 500 mm |
| Current Model Y, 2025+ | 26 / 20 in; 650 / 500 mm |
These are Tesla's published nominal inch/mm sizes, not exact unit conversions. The same lengths across generations do not establish that the arm connection or an aftermarket adapter is unchanged. Check your own regional manual and the fitted connector, especially on a refreshed vehicle or one with replacement arms.
For Model S, Model X, Cybertruck or Roadster, select the matching generation in Tesla's owner manuals. Do not transfer the Model 3/Y sizes or installation overview to those vehicles. The earlier universal size and rear-wiper recommendations have been removed because they were not supported by the cited documentation.
Clean first or replace now?
| What happens | Next step |
|---|---|
| Rubber is split, torn or damaged | Replace the damaged blade; do not wait for a calendar interval. |
| Smearing began after a wash or treatment | Clean the glass and blade using the vehicle manual's approved method before buying. |
| Cleaning does not restore effective wiping | Check the correct replacement application and connector. |
| A new blade chatters or leaves an unwiped area | Recheck the part, retention and contamination before buying another pair. |
| Arm is damaged, loose or moves abnormally | Have the mechanism assessed; this is not just a blade swap. |
| Auto behaves unexpectedly but manual wiping clears the glass | Investigate settings/visibility separately from blade wear. |
Tesla lists wax, ice and certain washer-fluid additives among possible contaminants, and warns against washer fluids containing water-repellent or bug-wash formulations. Use a product approved for the relevant glass/rubber surfaces, following the manual and label. A hydrophobic treatment is not a blanket cure for chatter. Model Y cleaning and fluid guidance.
If visibility is inadequate, stop safely rather than continuing to test a setting. Release frozen blades according to the vehicle's cold-weather instructions before operating them.
Two purchasing routes
Tesla replacements: confirm the vehicle and side
The Tesla Model 3 wiper-blade listing sells one blade, selected as driver or passenger side. It is not automatically a pair. Tesla currently lists compatibility with all Model 3 vehicles; verify your vehicle and selected side when ordering.
For other models, use the Tesla Shop with the registered vehicle or ask Tesla to confirm the application. These are non-affiliate links. This is the simpler route when an aftermarket catalog does not cover your exact build or the connector is uncertain.
Bosch alternatives: use the catalog application
Bosch's 2025 North American Wiper Blade Catalog, printed page 186 (PDF page 204), lists these front sets:
- Model 3, 2017–2024: OE-style set 3397014116.
- Model Y, 2020–2024: OE-style set 3397014621.
It also lists individual ICON 26XT + 19XT for those Model 3 years and 26XT + 20XT for those Model Y years. These are complete codes; “Bosch ICON 26-inch” alone is insufficient. Bosch application catalog.
Do not extend these entries to 2025+ cars without current fitment confirmation. Verify year, steering side/market, connector, adapters and whether the offer contains one blade or a pair. A seller grouping Model 3 and Y together does not override their differing specifications.
Search Amazon US for Bosch 3397014116 — Model 3 catalog candidate for the years above.
Search Amazon US for Bosch 3397014621 — Model Y catalog candidate for the years above.
These are searches, not a verified seller's offer. Results may contain other part numbers, singles and sponsored alternatives. Match the full number on the package and confirm fitment. Compare the complete delivered cost with Tesla's two individual blades; no fixed savings or universal-fit claim is made.
Replacing Model 3/Y blades: installation overview
Read your vehicle's manual first. For the current Model 3 procedure:
- Park and turn the wipers off. Select Controls → Service → Wiper Service Mode.
- Lift the arm only enough to access the connection. It does not lock upright; hold it and protect the windshield with a towel.
- Hold the arm, release the tab and slide off the blade as shown in the manual. Do not force an unfamiliar connector.
- Fit the correct blade until retained. Perform the specified push-pull check, then carefully lower the arm.
- Return the arms safely to the glass before switching Wiper Service Mode off. Clear tools and hands before checking operation.
This is the owner-accessible Wiper Service Mode, not an instruction to enter the diagnostic Service Mode menu. Tesla Model 3 replacement instructions.
Never let a bare arm spring onto the windshield. If a blade will not lock, stop and check the part/adapter rather than trimming plastic or bending the arm. Keep the old blade for comparison until the replacement is secured.
Check the result before driving in rain
Confirm the blades are secure, clear nearby trim and wipe normally on a wetted windshield while parked. Resolve detachment, contact with trim or inadequate wiping before driving. Do not assume the blade needs an unsupported calibration cycle or generic sensitivity adjustment.
Keep the packaging and part numbers until verified. If the symptom remains, record the vehicle build, blade codes, recent glass treatments and whether it occurs in manual wiping as well as Auto. This gives a repairer a better starting point than another speculative purchase.
