🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Put the wipers in “service position”

• Turn the ignition on, then turn it off (so the car is “awake,” then shut down).
• Within a few seconds, press and hold the wiper stalk down (the single-wipe position) for about 3-5 seconds.
• The wipers should move up and stop partway on the windshield. This is service position (a mode that parks the wipers where you can lift them).

Step 2: Lift the wiper arm carefully

• Use your hand to gently lift one wiper arm away from the glass.
• Keep the microfiber towel on the glass below the arm.

Step 3: Remove the old wiper blade

• At the point where the blade connects to the arm, locate the small release tab/clip.
• Press the tab with your fingers; if it’s tight, use a small flat trim tool to gently help press the tab. (A trim tool is a small plastic prying tool that helps you avoid scratching parts.)
• Slide the blade downward (toward the base of the wiper arm) until it unhooks, then remove it.

Step 4: Install the new wiper blade

• Match the new blade to the old one (length and connector style should match).
• Slide the new blade onto the arm until you hear/feel a solid “click.”
• Gently tug on the blade to confirm it’s locked in place.

Step 5: Repeat for the other side

• Use the same steps on the second wiper.
• Replace both blades together for even wiping.

Step 6: Return wipers to normal parked position

• Lower both wiper arms back onto the windshield gently.
• Turn the ignition on and briefly tap the wiper stalk once to let the system re-park the wipers normally.

✅ After Repair

• Test washer + wipers and confirm both blades wipe smoothly without streaks or skipping.
• Listen for any clicking (can mean the blade isn’t fully clipped in).
• Clean the windshield with glass cleaner for best results.
