How to Change the Windshield Wipers on a 2001 Silverado
- 1). Grab the wiper blade and pull it upward from the windshield until the arm locks in a vertical position.
- 2). Look at the center of the wiper blade -- where the blade attaches to the arm -- and locate the plastic clips securing the blade to the arm.
- 3). Press the tab on the plastic clip and pull the blade downward until the blade is free from the arm.
- 4). Position a new wiper blade so that the hook on the arm lines up with the rounded part of the plastic clip. Press the wiper upward until the locking tab clicks into place.
- 5). Lower the wiper blade onto the windshield.
- 6). Repeat Steps 1 through 5 to replace the windshield wiper on the other side of the Silverado.
