🔧 Front Wiper Blade Replacement

Your Sierra uses a simple hook-style wiper arm, so this is a quick blade swap with no special programming or scan tool work. Replacing both blades at the same time keeps streaking and noise from returning unevenly.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the wiper arm

• Use your hand to gently lift the front wiper arm away from the windshield.
• Hold the arm steady so it does not spring back.
• Protect the glass while working.

Step 2: Remove the old blade

• Use your fingers to find the small release tab where the blade connects to the hook.
• Press the release tab and slide the blade downward to unhook it from the arm.
• If it is tight, wiggle the blade gently while pulling it off.

Step 3: Install the new blade

• Take the new blade and line up the hook with the adapter opening.
• Slide the blade onto the hook until it clicks into place.
• Pull lightly on the blade to make sure it is locked in.

Step 4: Repeat on the other side

• Repeat the same removal and installation process for the second wiper blade.
• Make sure both blades match side to side and sit flat on the arm.

Step 5: Lower the arms and test

• Carefully lower both wiper arms back onto the windshield.
• Turn the ignition on and run the washer/wiper system for a quick test.
• Check that both blades sweep smoothly and do not chatter or leave streaks.

✅ After Repair
