I have a few questions about A/C that I've always wanted to know the answers.

Does turning up the fan to a faster speed waste more gas and therefore reduces performance more? You're pumping more A/C cold air in and using the engine and gas more for the A/C if the fan is on max?

The AUTO and MANUAL LEDS on the A/C button don't really mean auto or manual. AUTO is filtrated outside air and manual is recirculation. Why are they called auto and manual? And according to
GrecianVolvo, one should turn off the recirc button once the A/C gets going. Why not use recirc (manual) or outside air (auto) when it gets going?
