Step-by-Step Instructions

Follow these steps carefully

Confirm the sizes and buy the blades

The 2014–2024 Infiniti Q50 takes a 26-inch blade on the driver side. The passenger side is 17 inches on most fitment charts, though a few list 16 inches — measure your old passenger blade with a tape before buying to be sure.

Park the wipers and lift the driver-side arm

Turn the Q50 off and confirm the wipers are parked at the base of the windshield. Do one side at a time so the 26-inch driver blade and the shorter passenger blade never get confused.

🔧 Mechanic's note — Tom Becker

Quick word from me — I've been under there: Do one side at a time so the 26-inch driver blade and the shorter passenger blade never get confused.

Release the old driver-side blade from the offset hook

The Q50 uses an offset hook-style arm. Lift the driver-side arm, then locate the release tab where the blade's adapter sits in the hook. Press the tab and slide the long 26-inch blade down out of the hook. Hold the bare arm with your other hand the whole time — it is under strong spring tension and will crack the glass if released.

Prep the new 26-inch blade

Pull the protective sleeve off the new blade without touching the rubber edge. Make sure the blade's adapter is configured for a hook arm — most aftermarket blades include a small adapter you snap into the hook position.

🔧 Mechanic's note — Tom Becker

In my experience, small thing, big difference: Make sure the blade's adapter is configured for a hook arm — most aftermarket blades include a small adapter you snap into the hook position.

Hook the new blade on and check the lock

Slide the new 26-inch blade into the arm's hook and pivot it up until the adapter clicks. Ease the arm back down onto the windshield, controlling it all the way.

Install the passenger blade

Repeat the tab-release and hook install for the passenger blade — 17 inches on most Q50s, 16 on some. Double-check: the 26-inch blade belongs on the driver side; a short blade on the wrong side leaves a large unwiped area.

Test with washer fluid

Start the car, spray washer fluid, and run the wipers through intermittent, low, and high speeds. The big 26-inch driver blade should clear its full arc without streaks or skips at the tip. If the passenger blade misses the outer edge of the glass, you may have bought a 16-inch blade for a 17-inch car — measure and swap before driving in rain.

All Done!

Test your repair before closing everything up. If something doesn't work right, double-check your steps.

⚠️ Common Mistakes to Avoid

• Buying two 26-inch blades — the Q50's passenger side is 17 inches or less
• Trusting a parts-store lookup without measuring, when charts split between 16-inch and 17-inch passenger blades
• Installing the hook adapter backward so the blade will not click in
• Letting the bare arm snap back onto the windshield while the blade is off

Tools You'll Need

26-inch driver blade and 17-inch (measure first — some charts say 16-inch) passenger blade with hook adapters Tape measure Clean microfiber cloth Glass cleaner Folded towel (to protect the windshield while blades are off)

⚠️ Safety First!

• Never let go of the bare wiper arm — the spring can slam it into the windshield hard enough to crack it.
• Keep the ignition and wiper switch off while your hands are on the arms.
