How do I turn on my air conditioner in a 2009 saturn

There is a button labeled A/C on the front of the A/C and other buttons on the dash. press that, usually lights up n green if A/C on....if light not on, then just the regular outside air is coming through. The A/Cn the Aura works excellent so I'm sure once you find the button there on the dash, you'll lots of cool air conditioned air.
