The AC system itself will continue to work... it won't be as efficient, since one of the functions of the AC system is to remove humidity from the passenger compartment, and an open window is constantly reintroducing it back into the passenger compartment. It won't effectively cool with the windows open, since warmer air is going to be constantly going into the vehicle via the windows. But the AC system will still function the way it normally does.
Central air conditioning systems are designed to provide ventilation by bringing in outside air. Leaving a window open would tend to defeat the cooling effect.
If you have access to a window, you can get a window-mounted air conditioning unit or one with a pipe to go out the window. Self-contained AC units don't work well because they have no place to dump the warm air except back into the office.
At highway speeds yes, in city driving no.
You can buy a window air conditioning unit anytime of the year. You just need to go to your local hardware store like Home Deport or Lowes and purchase it there.
A window air conditioning unit is designed to fit into a window opening. these can normally be fit into a hole made into the wall as well. They are definitely a cooling system and blow dehumidified cold air and in the case of reverse cycle hot air.

If you mean by saving energy - a BIG start would be to stop using air-conditioning units in houses ! If people are too warm - open a window !
