🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the Driver-Side Wiper Arm

• Use your hands to gently lift the driver-side wiper arm away from the windshield until it stays raised.
• Place a clean microfiber towel on the windshield under the raised arm as a cushion.
• Protect the glass first.

Step 2: Find the Blade Release Tab

• Use your fingers to locate the small release tab where the wiper blade connects to the hook-shaped end of the wiper arm.
• The hook-shaped end is called a J-hook. It holds the blade by wrapping around the blade adapter.

Step 3: Remove the Old Driver-Side Blade

• Use one hand to press the release tab on the blade adapter.
• Use your other hand to slide the wiper blade downward toward the base of the wiper arm.
• Once the blade clears the J-hook, pull it away from the arm.
• Do not release the bare wiper arm without a blade installed.

Step 4: Install the New Driver-Side Blade

• Use your hands to line up the new 22" driver-side wiper blade with the J-hook on the wiper arm.
• Slide the blade upward into the hook until it clicks into place.
• Gently tug the blade by hand to confirm it is locked onto the arm.
• No torque spec applies because this blade snaps on by hand.

Step 5: Lower the Driver-Side Wiper Arm

• Use both hands to slowly lower the wiper arm back onto the windshield.
• Remove the microfiber towel after the blade is safely resting on the glass.

Step 6: Replace the Passenger-Side Blade

• Use your hands to lift the passenger-side wiper arm away from the windshield.
• Place the clean microfiber towel under the arm to protect the glass.
• Press the release tab with your fingers.
• Slide the old blade downward out of the J-hook.
• Install the new 21" passenger-side wiper blade by sliding it into the hook until it clicks.
• Gently tug the blade by hand to confirm it is locked.
• Slowly lower the wiper arm onto the windshield.
• No torque spec applies because this blade snaps on by hand.

Step 7: Test the New Wiper Blades

• Use the windshield washer switch on the wiper stalk to spray washer fluid onto the windshield.
• Turn the wipers on low speed and watch both blades sweep smoothly.
• If a blade skips, chatters, or leaves a large streak, turn the wipers off and make sure the blade is fully clicked into the J-hook.
• Always test with washer fluid.
