🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the wiper arm safely

• Use your hands (no tool) to lift one wiper arm away from the windshield until it stays up.
• Place the microfiber towel under the arm area as protection.
• Do one side at a time.

Step 2: Release the old blade from the J-hook

• Hold the wiper arm with one hand, and with the other hand rotate the blade so it’s roughly perpendicular (a “T” shape) to the arm.
• Look where the blade attaches: it’s a J-hook (a J-shaped metal hook on the arm that slides into the blade adapter).
• Press the small release tab on the blade adapter using your thumb. If it’s tight, use a small flathead screwdriver to gently press the tab.
• Slide the blade down and out of the J-hook, then remove it completely.

Step 3: Install the new blade

• Confirm you have the correct side: Driver 22" or Passenger 21".
• Line up the J-hook with the opening in the new blade’s adapter.
• Slide the blade onto the hook until it clicks/locks.
• Gently tug on the blade (by hand) to confirm it’s fully latched.

Step 4: Lower the arm and repeat on the other side

• Carefully lower the wiper arm back onto the windshield by hand—don’t let it drop.
• Repeat Steps 1–3 for the other front wiper blade.

Step 5: Quick function check

• Remove the microfiber towel.
• Turn ignition ON and briefly run the wipers with washer fluid to confirm smooth, quiet wiping.
