📋 Before You Begin

• 🅿️ Park on level ground and turn the ignition OFF.
• 🧼 Clean the windshield area where the blades sit.
• 📏 Verify sizes: look for the length printed on the old blade, or measure end-to-end with a tape measure.
• 🧩 Check the connector type on your old blade (the “connector” is the plastic clip that locks to the metal arm).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Move the wipers to service position (if needed)

• If your wiper arms won’t lift up easily (or they bump the hood), use the “service position” so the blades sit higher on the glass.
• Use this common Mazda procedure: turn ignition ON, then turn ignition OFF, then within 30 seconds move the wiper stalk to MIST (one quick swipe) twice.
• If your wipers do not move to a higher position, skip this step and carefully lift the arms as far as they allow.

Step 2: Lift the wiper arm safely

• Lift one wiper arm away from the windshield until it stays up.
• Place a microfiber towel on the windshield under the arm as protection.
• Work one side at a time.

Step 3: Release the old wiper blade from the arm

• Look for the small plastic release tab where the blade connects to the arm.
• Press the tab with your fingers; if it’s stubborn, use a small flathead screwdriver gently to press the tab.
• Slide the blade down/out of the arm hook/clip until it comes free.

Step 4: Install the new wiper blade

• Compare the new blade to the old one for length using a tape measure.
• If your new blade includes adapters, choose the one that matches your old blade’s connector shape.
• Slide the new blade onto the wiper arm until you hear/feel a solid click.
• Gently tug on the blade to confirm it’s locked in place.

Step 5: Lower the arm back onto the glass

• Hold the arm and lower it slowly onto the windshield (don’t let it drop).
• Remove the microfiber towel.

Step 6: Repeat for the other side

• Repeat Steps 2–5 for the other front wiper blade.
