Q: Defrost Windshield on 1998 Toyota Camry

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
To defrost my windshield I turn the dial that controls where the air is directed all of the way to the right that makes the air only come out of the windshield area and turn the temperature dial to red.. The AC button lights up. Is this the correct way? My friend says I am wrong and I should use the air direction button that shows the floorboard area and the windshield are and therefore the AC light does not come on. Which way is correct?

You want all the air directed to the windshield, and the A/C should be on. The A/C system removes moisture from the air, so it's important that it is on when trying to remove moisture from the windshield.
