• ⚠️ Do not run the wipers with no blades installed.
• ⚠️ If the wiper arm won’t lift freely, don’t force it—use the wiper “service position” steps below.
• Battery disconnect is not required.

📋 Before You Begin

• Park on level ground and shift to Park.
• Turn the ignition OFF.
• Place a microfiber towel on the lower edge of the windshield as a safety cushion.
• If the wiper arms hit the hood and won’t lift, use this common GM “service position” attempt: turn ignition ON, then OFF, then immediately move/hold the wiper stalk to a single-wipe (mist) position for 2–3 seconds to park the wipers higher. If it doesn’t work on your XT4, skip it and continue with the hood open.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the wiper arm safely

• Open the hood if needed for clearance.
• Lift one wiper arm up off the glass until it stays up on its own.
• Slide the microfiber towel (hand tool) under the arm’s contact area as protection.

Step 2: Remove the old wiper blade

• Find the connector where the blade attaches to the arm (usually a “J-hook” or push-button style).
• If there’s a small locking tab, press it with your thumb; if it’s stiff, use a small flat-blade screwdriver gently to depress the tab.
• Slide the blade down and off the end of the wiper arm.
• Don’t let the bare arm touch glass.

Step 3: Install the new wiper blade

• Confirm the new blade matches the old blade length before installing.
• Slide the new blade onto the wiper arm connector until you hear/feel a click.
• Gently tug the blade to confirm it’s locked in place.

Step 4: Lower the wiper arm carefully

• Hold the arm firmly and lower it back onto the windshield slowly.
• Remove the microfiber towel.

Step 5: Repeat on the other side

• Repeat Steps 1–4 for the other front wiper blade.
