š Before You Begin
- š æļø Park on level ground and turn the ignition OFF.
- Place a microfiber towel on the lower windshield area under the wiper arms.
- Uncommon term: the connector is typically a J-hook style (a hook-shaped end of the wiper arm that the blade slides onto).
šØ Step-by-Step Instructions
Follow these steps in order:
Step 1: Lift and support the wiper arm
- Use your hands to lift the driver-side wiper arm away from the windshield until it stays up.
- Keep the microfiber towel in place in case the arm drops.
Step 2: Unlock the old wiper blade
- Rotate the wiper blade so you can see the connector where it meets the arm.
- Press the small locking tab on the connector with your fingers.
- If the tab is stubborn, gently help it with a small flathead screwdriver (donāt pry hard).
Step 3: Slide the old blade off the arm
- While holding the lock tab pressed, slide the blade down and off the hook.
- Set the old blade aside.
Step 4: Install the new blade
- Remove the new blade from its packaging.
- If your new blade includes multiple adapters, choose the one that matches the factory connector (most commonly J-hook).
- Slide the new blade onto the hook until you hear/feel a click.
- Give the blade a gentle tug to confirm itās locked.
- Tip: āClick + tug testā prevents fly-off.
Step 5: Lower the arm carefully
- Use your hand to lower the wiper arm back onto the windshield slowly.
- Remove the microfiber towel.
Step 6: Repeat on the passenger side
- Repeat Steps 1ā5 for the passenger-side blade.
- Make sure the passenger blade length is 18" and the driver blade is 26".
ā After Repair
- Turn the ignition ON and run the washers for a few seconds.
- Verify both blades wipe smoothly with no skipping, streaks, or unusual noises.
- If thereās chatter, clean the windshield with glass cleaner and a microfiber towel.
