Method 1: Push-Button or Hook-Type Release:
1. Lift the wiper arm: Lift the wiper arm away from the windshield. You may need to gently pry it up with your fingers or a small, flat, plastic tool (to avoid scratching the paint).
2. Locate the release: Look closely at the connection point where the wiper arm meets the wiper blade. You'll see either a small button you push or a small tab or hook that needs to be manipulated.
3. Release the blade: Push the button or manipulate the tab/hook to release the wiper blade from the wiper arm. The blade should then slide or lift off.
Method 2: Pinch-Type Release:
This is less common but possible. Instead of a button or hook, you might have to squeeze two parts of the wiper arm connection together to release the blade. Again, lift the wiper arm first. Look closely at the connection for a narrow space where you can pinch.
Important Considerations:
* Always lift the wiper arm first. Trying to force anything before lifting will likely damage the wiper arm.
* Use the right tool. If you need to pry, use a plastic trim removal tool or a flat, dull object (like a plastic putty knife) to avoid damaging the wiper arm or the paint.
* Be gentle. These connections are relatively fragile and can break if you use excessive force.
* Consult a diagram: If you're still having trouble, look up a wiper blade replacement diagram specifically for a 1998 Buick LeSabre online. A visual aid can be incredibly helpful.
* If you're unsure: If you're uncomfortable performing this task yourself, it's always best to take your vehicle to a qualified mechanic or auto parts store where they can assist you. They can also advise on the proper replacement wiper blade for your vehicle.
Remember to install the new wiper blade following the reverse process. Make sure it clicks securely into place.
