How do you remove the wiper arm from a 2004 Chevy Silverado 1500?

To remove the wiper arm from a 2004 Chevy Silverado 1500, first, lift the wiper arm away from the windshield. Then, locate the small cap at the base of the wiper arm and gently pry it off with a flathead screwdriver to expose the mounting nut. Use a socket wrench to remove the nut, and then pull the wiper arm straight off the wiper shaft. Be careful not to damage the windshield or the wiper motor during this process.
