🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the wiper arm

• Lift the driver-side wiper arm up and away from the windshield until it stays up.
• Keep the microfiber towel underneath as a safety cushion.

Step 2: Remove the old wiper blade from the J-hook

• At the middle of the blade, find the connector where the blade meets the arm.
• Press the small release tab on the connector with your finger while sliding the blade down toward the base of the arm to unhook it.
• A “J-hook” is the curved, hook-shaped end of the wiper arm that the blade clips onto.

Step 3: Install the new wiper blade

• Align the new blade’s connector opening with the J-hook end of the arm.
• Slide it into place until you hear/feel a click.
• Gently tug on the blade to confirm it’s locked in.

Step 4: Lower the wiper arm carefully

• Lower the wiper arm back onto the windshield slowly by hand.
• Remove the microfiber towel.

Step 5: Repeat for the passenger side

• Repeat Steps 1–4 for the passenger-side wiper blade.
• Install the correct size blade on each side (driver vs passenger).

✅ After Repair

• Turn the ignition on and run the wipers on low speed to verify smooth wiping and no skipping.
• Top off washer fluid and test the washers to confirm the spray hits the windshield correctly.
• If you hear chatter, clean the windshield and blades, then re-test. Dirty glass can mimic bad blades.
