Replacing the wiper blades on the 2018 GMC Sierra 1500 is really simple, since both the driver's side and passenger side use the same ones for the front windshield: 22 inchers. You can pick up the Bosch Envision 22 inch Beam Wiper Blade, part #EN22OE from AutoZone for $32. To change Your wipers, first, locate the small square button on Your wiper arm, and press it in. Now, grasp on the wiper blade and pull it towards You; the entire blade will pull out of the square housing. To install the new wiper blade, You'll want to push the rectangular housing into the hole with the release button and stop when You hear a satIS Fying snap... Or, a click, which may or may not be as satIS Fying.
