1. Lift the wiper arm: Most wipers have a small tab or release lever under the wiper arm where it connects to the wiper arm spindle. Locate this. You might need to gently pry it up, *carefully* using a flat-head screwdriver or similar tool. Sometimes, it's simply a matter of pushing the lever while lifting the arm.
2. Rotate the wiper arm: Once the release is engaged, lift the wiper arm away from the windshield. Often, you'll need to rotate the arm slightly, usually 90 degrees away from the windshield to clear the connection. Some wipers may require more or less than 90 degrees.
3. Remove the wiper blade: Once the arm is free from the spindle, the wiper blade itself should simply slide off or detach from the wiper arm. The exact mechanism will depend on the type of wiper blade used. Consult your owner's manual or a parts store if you're unsure.
Important Considerations:
* Pressure: Don't use excessive force. If it's not budging, you're likely missing a release mechanism or applying pressure in the wrong direction.
* Rust: If your car is older, rust may be an issue. Penetrating oil (like PB Blaster) applied to the connection point a few hours before attempting removal can help loosen things up.
* Photos: Before you start, it's a good idea to take photos of the wiper arm's position and how it connects to the spindle. This will help you put it back on correctly.
* Repair Manual: A repair manual specific to your 1994 Buick LeSabre will provide the most accurate and detailed instructions.
If you're uncomfortable performing this task yourself, it's a relatively inexpensive job for a mechanic to handle.
