2019 Toyota Highlander Wiper Blade Sizes & Replacement Guide

Keeping the windshield of your 2019 Toyota Highlander clear is essential for safe driving, whether you are dealing with a sudden summer downpour or winter slush. Finding the correct wiper blade sizes and knowing how to install them can save you a trip to the dealership. Below is the complete guide to the wiper blade sizes, attachment styles, and replacement procedures for the 2019 Toyota Highlander.

Quick reference

Here are the exact wiper blade sizes, attachment types, and OEM part numbers for the 2019 Toyota Highlander.

Best aftermarket replacements

If you prefer to use aftermarket blades rather than sourcing OEM Toyota parts, there are several premium and budget-friendly options available. Here are some of the most popular cross-references for the 2019 Highlander:

• Bosch ICON: Premium tier. Known for an exclusive rubber compound that resists heat and ozone deterioration. Excellent for all-weather durability.
• Rain-X Latitude: Premium tier. These water-repelling blades apply a rain-repellent coating to the windshield as they wipe.
• Trico Force: Mid-to-Premium tier. Features a swept-wing spoiler design that reduces wind lift at highway speeds.
• Michelin Stealth: Mid-tier. A hybrid design that offers the pressure distribution of a conventional frame with the snow/ice resistance of a beam blade.
• PIAA Si-Tech: Premium tier. Silicone blades that offer incredible longevity and leave a water-repellent barrier with every wipe.

Attachment style

The front wiper blades on the 2019 Toyota Highlander use a standard 9x3 J-hook attachment. This is the most common and easiest attachment style in the automotive industry, meaning almost any aftermarket blade will fit without the need for specialized adapters.

The rear wiper uses a specialized plastic arm attachment (often referred to as Roc Lock 3). When buying a rear blade, ensure it specifically notes compatibility with Toyota/Lexus rear wiper arms, as standard J-hooks will not work on the back window.

How to install

Replacing the front wiper blades on your Highlander is a straightforward process:

1. Lift the wiper arm: Carefully pull the wiper arm away from the windshield until it locks in the upright position.
2. Remove the old blade: Press the small plastic tab located where the blade meets the J-hook. Slide the blade down toward the base of the wiper arm to unhook it.
3. Install the new blade: Align the new wiper blade with the J-hook. Slide the hook into the blade's connector and pull up until you hear a distinct click.
4. Test: Gently lower the arm back to the windshield and test the wipers with wiper fluid to ensure they are secure and functioning.

Note for the rear wiper: Lift the plastic cover at the base of the rear arm if necessary. Rotate the blade away from the arm until it pops out of the C-shaped clip, then snap the new 12-inch blade into place.

When to replace

For optimal visibility, you should replace your wiper blades every 6 to 12 months. Sun, ozone, and freezing temperatures degrade the rubber over time. Watch for these common signs that your blades are failing:

• Streaking: Leaving bands of water across the glass.
• Chattering: The blade skips or stutters across the windshield, making a loud noise.
• Smearing: Spreading water and debris rather than clearing it.
• Splitting: Visible cracks or tears in the rubber squeegee.
