⚠️ Safety & Precautions
- ⚠️ Don’t let a bare wiper arm snap onto the windshield—place a towel on the glass as protection.
- ⚠️ Work with the ignition OFF and wipers turned OFF.
- ⚠️ Lift the wiper arm gently; don’t force it past its normal hinge range.

đź“‹ Before You Begin
- Park your Impala on level ground and turn the ignition OFF.
- Put a microfiber towel across the lower windshield to protect the glass.
- Use a tape measure (inch) to confirm each blade length, or read the size printed on the old blade.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Lift the wiper arms safely
- Place the microfiber towel on the windshield under the wiper arms.
- Lift the driver-side wiper arm up until it stays in the “service” position.
- Repeat for the passenger-side arm.
- Hold the arm while removing the blade.
Step 2: Identify the blade attachment style
- Look where the blade connects to the arm (the “adapter”).
- Most blades use either a J-hook (a hook-shaped end) or a pinch-tab/top-lock connector (a button/tab you squeeze or press).
Step 3: Remove the old blade (J-hook style)
- Rotate the blade so it sits roughly perpendicular to the wiper arm.
- Press the release tab on the adapter (use your fingers; if stuck, gently assist with the small flathead screwdriver).
- Slide the blade down toward the open end of the hook, then unhook it and remove.
Step 4: Remove the old blade (pinch-tab/top-lock style)
- Locate the locking tab/button on the adapter.
- Press the tab (use fingers; if needed, gently help with the small flathead screwdriver).
- While holding the tab, slide the blade straight off the arm.
Step 5: Install the new blade
- Match the new blade to the side you’re working on (driver vs passenger). Confirm length with the tape measure (inch).
- Attach the new blade to the arm using the same connector type you removed:
- For J-hook: slide the new blade adapter into the hook and pull until you hear/feel it click.
- For pinch-tab/top-lock: slide the blade onto the arm until it clicks/locks.
- Gently tug on the blade to confirm it’s locked in place.
Step 6: Lower the arms carefully
- Lower each wiper arm back onto the windshield gently.
- Remove the microfiber towel.
âś… After Repair
- Turn the ignition ON and run the washers for 2–3 wipes to verify smooth operation.
- Check for skipping, streaking, or one side not wiping fully (often caused by a blade not fully clicked in).
- If there’s chatter, clean the windshield and blade rubber with a damp microfiber towel.
