🔧 Front Windshield Wiper Blades - Replacement

Replacing the front wiper blades on your Sierra is a quick job. You’ll swap out both blades and make sure the new ones lock into place securely so they clear rain properly and don’t chatter on the glass.

Difficulty Level: Beginner | Estimated Time: 0.25-0.5 hours


⚠️ Safety & Precautions

  • Turn the ignition off and keep the wipers in the rest position before starting.
  • Carefully support each wiper arm while the blade is off so it does not snap back against the windshield.
  • Do not let the bare wiper arm touch the glass.
  • No battery disconnect is required.

🔧 Required Tools

You'll need the following tools for this repair:

  • Clean microfiber towel
  • Safety glasses
  • Gloves

🔩 Required Parts

  • Front wiper blade - Driver: 22", Passenger: 22" - Qty: 2

📋 Before You Begin

  • Park on level ground and set the parking brake.
  • Make sure the ignition is off.
  • If your wipers are stuck in an unusual position, cycle them off and let them return to the parked position first.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift the first wiper arm

  • Lift the driver-side wiper arm away from the windshield.
  • Hold the arm steady with one hand so it does not snap back.
  • Protect the glass.

Step 2: Remove the old blade

  • Press the small release tab on the blade adapter.
  • Use your fingers to slide the blade down and off the arm hook.
  • If it is stuck, gently wiggle it while keeping pressure on the release tab.

Step 3: Install the new blade

  • Align the new blade with the wiper arm hook.
  • Use your fingers to slide the blade into place until it clicks.
  • Pull lightly on the blade to confirm it is locked.

Step 4: Repeat on the other side

  • Repeat the same removal and installation steps on the passenger-side wiper arm.
  • Make sure both blades are seated the same way.

Step 5: Lower the arms and test

  • Carefully lower both wiper arms onto the windshield.
  • Turn the ignition on and run the wipers with washer fluid.
  • Check that both blades sweep smoothly with no clicking or streaking.

✅ After Repair

  • Test the washer spray and wiper sweep on the windshield.
  • Make sure both blades park correctly at the bottom of the glass.
  • If they streak, clean the windshield with glass cleaner and recheck the blade fit.
