Well nitemare, you don't say how many miles are on your Commander, but it can't hurt to get your A/C checked out. It should run colder on the "max" setting since it is not taking out side air in and is just recirculating inside air only. On the regular a/c setting it is taking in out side air and cooling it, making it not as cold as "max."
I guess there are different schools of thought with the gas mileage aspect. Some say your gas mileage is the same if your windows are closed and a/c on as the a/c off with your windows open.
