🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Protect the Windshield

• Use the folded microfiber towel and place it on the windshield under the wiper blade you are replacing.
• This protects the glass if the wiper arm slips from your hand.
• Never trust the spring-loaded arm.

Step 2: Lift the Driver-Side Wiper Arm

• Use both hands to gently lift the driver-side wiper arm away from the windshield.
• Stop when the arm holds itself up.
• Do not pull the arm sideways because it can bend.

Step 3: Release the Old Driver-Side Wiper Blade

• Use your thumb to press the small release tab on the wiper blade connector.
• The release tab is the small plastic latch that locks the blade to the arm.
• Slide the old blade down and away from the curved hook on the wiper arm.
• Use the folded microfiber towel to keep the bare arm from touching the glass.

Step 4: Install the New Driver-Side Wiper Blade

• Use your hands to line up the new 22-inch blade with the hook on the driver-side wiper arm.
• Slide the blade into the hook until you hear or feel a click.
• Gently tug the blade with your hand to confirm it is locked.
• Lay the wiper arm carefully back onto the windshield using the folded microfiber towel as protection.

Step 5: Replace the Passenger-Side Wiper Blade

• Use both hands to lift the passenger-side wiper arm away from the windshield.
• Use your thumb to press the release tab on the old blade.
• Slide the old blade down and away from the curved hook.
• Use your hands to install the new 20-inch blade into the hook until it clicks.
• Gently tug the blade with your hand to confirm it is locked.
• Lower the wiper arm carefully onto the windshield.

Step 6: Check Blade Position

• Use your hands to make sure both blades sit flat against the windshield.
• Confirm the rubber wiping edges are not folded over or twisted.
• Remove the folded microfiber towel from the windshield.
