1. Prepare:
* Park the car: Ensure your car is parked on a level surface and the ignition is off.
* Gather tools: You'll likely only need your hands, but having a small flat-head screwdriver or trim tool might be helpful if the wiper arms are stubborn. A towel is also useful to protect your car's paint.
2. Release the wiper arm:
* Locate the release tab or button: Most Impalas have a small tab or button located near the base of the wiper arm, where it connects to the wiper spindle. This is usually on the underside of the arm. This is the critical step where models vary slightly. Look closely at the base of the wiper arm – this is where you’ll find the mechanism.
* Lift the arm: Using your hand, gently lift the wiper arm away from the windshield. You may need to apply some slight upward pressure. Sometimes a gentle wiggle is needed.
* Locate the release: Once the arm is slightly lifted, you should see the release tab or button.
* Push the tab or button: While holding the wiper arm up, push the tab or button to release the arm from the spindle.
3. Remove the wiper blade:
* Once the arm is detached from the spindle, the wiper blade itself usually just pulls off. You might find a small clip securing it to the arm. If there is a clip, gently pry it open.
Important Considerations:
* Wiper arm position: Some recommend lifting the wiper arm to its highest position before attempting to release it. This can sometimes make access to the release mechanism easier.
* Stubborn arms: If the wiper arm is difficult to remove, do *not* force it. Use a small flat-head screwdriver or trim tool to gently pry the release tab or button. Be extremely careful to not scratch the paint. If you still can't remove it after some gentle prying, consult a professional.
* Year-specific differences: As mentioned, the exact location and method of release can vary depending on the year and model of your Impala. Checking your owner's manual or searching online for videos specific to your Impala's year is strongly recommended.
Installing new wipers: The process is essentially reversed. Make sure the new wipers are correctly aligned and the arm is firmly attached to the spindle before lowering it.
Remember, if you are uncomfortable performing this task, it's always best to take your Impala to a professional mechanic. They have the tools and expertise to do it quickly and safely.
