I have a button on my climate control panel that i have no idea what it is. Its got 2 circles one with an A inside it. any ideas??

It means Automatic, recirculation, i.e when stopped in traffic it automatically switches from fresh air intake to recirculated air to avoid drawing in smog crap etc..... I left mine on A all the time and it just switches as when it needs too....

But when you press it the light on the left of the switch comes on and press it again and it changes to light on the right, whats that for?

Auto and manual mode.
