What is the best way to run my AC?

 Two examples:
Let's imagine that your car has been sitting in the supermarket car park in full sunshine for a couple of hours and is too hot to touch. A reasonable result can be achieved by following this.
1. Open all the doors whilst you load up the car
2. Once in the car, start the engine, run the windows down, set the blowers to maximum, AC on (ensure the Econ button is OFF), any temperature controls to the lowest temperature setting, fresh air (not recirc) and air directed through the Face Level Vents.
3. Once you have blasted the hot air out of the open windows and filled the car with colder air, shut the windows and turn the Recirculation control ON (simply marked as Max on some models).
4. Keep the settings this way until the fabric of the inside of the car has cooled down and then either reduce the blower speed or turn the Recirc control to Fresh Air whichever you choose to do, or perhaps both.
5. Once the inside of the car is really cool, turn the blowers down a little further to suit your comfort and perhaps turn the Face Level Vents upwards to direct the cool air over your head and come down in the rear of the car. Alternatively to use the AC to demist the car the technique is quite different.
1. If the car is already misted up then simply turn on the AC, air directed to screen, blowers to highest speed, fresh air selected and the heat turned to maximum. Many cars simply have a demist button that does all this for you, but try it out as some are only a heated screen, use of the AC will be far quicker.
2. If the weather is warm but the car has misted up, use full heat on the screen together with the AC until it is safe to back the heater off and reduce the blower speed. Continue to use the AC in Fresh Air mode (Recirc OFF) for best demisting.
