🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the driver-side wiper arm

• Use your hand to gently lift the driver-side wiper arm away from the windshield.
• Place a microfiber towel on the glass under the arm for protection.
• Let the arm rest safely above the glass.

Step 2: Remove the old driver-side blade

• Find the small release tab where the blade connects to the arm.
• Press the release tab and slide the blade downward to remove it from the hook-style arm.
• If it sticks, wiggle the blade gently while keeping the arm steady.

Step 3: Install the new driver-side blade

• Align the new 28 inch blade with the arm hook.
• Slide the blade onto the hook until it clicks into place.
• Pull lightly on the blade to confirm it is locked in.

Step 4: Repeat on the passenger side

• Lift the passenger-side arm carefully and protect the glass with the towel.
• Press the release tab and remove the old blade using the same hook removal method.
• Install the new 20 inch blade until it clicks securely.

Step 5: Lower both arms and check the fit

• Lower both wiper arms gently back onto the windshield.
• Make sure each blade sits flat against the glass.
• Check that the left and right blades do not interfere with each other.
