Attachment style

The 2020 Toyota Highlander uses a push-button (also called top-lock) front wiper arm. Most quality aftermarket blades include a top-lock adapter in the box. The rear wiper also uses a small push-button style specific to rear arms.

• Front: Push-button/top-lock connector (commonly 19 mm). Use the included OE-style adapter from your blade kit.
• Rear: Compact push-button rear connector; choose a rear-specific 12-inch blade.

If your vehicle has a different arm (rare), such as J-hook or side pin, use the adapter supplied with the blade kit and follow the brand’s insert for that connector.

How to install

1. Prepare the new blades

• Verify sizes: 26" driver, 20" passenger, 12" rear. Identify the top-lock adapter in the package.

2. Position the arms

• Turn off ignition and set the wipers to the service position if your Highlander allows it, or gently lift the arms away from the windshield.

3. Remove the old blade (front)

• Press the push-button on the top-lock and slide the blade downward off the arm stub.

4. Attach the new blade (front)

• Snap the adapter onto the blade if not preinstalled, align the top-lock with the arm stub, and push until it clicks. Tug lightly to confirm it’s locked.

5. Rear blade

• Open the rear arm from the glass, press the small release tab/button, and slide the old blade off. Slide the new 12" blade on until it clicks.

6. Test

• Lower arms carefully onto the glass. Cycle washers/wipers to check for secure attachment and clean sweep.

Note: If your connector looks different, consult the adapter chart included with your blades (J-hook, side pin, bayonet, or push-button variants may require a different clip).

When to replace

• Interval: Every 6–12 months, or sooner in harsh sun, snow, or if parked outdoors.
• Signs it’s time: Streaking, chattering, skipping, smearing, or frayed rubber edges. Reduced nighttime visibility and missed wipe areas are also indicators.

Pro tip: Clean the rubber edges periodically with glass cleaner and a lint-free cloth to extend life.
