Only when on "auto" but it's just acting like the thermostat in your house, keeping the car at a chosen temp. Wether it cycles the a/c or heater depends on the conditions..

So are you saying that If it on auto and have the A/C on that it will acutally not use the A/C when it doesn't need to, thus saving the drag on the engine? I think the A/C is always on when the light is on.
