The upper deck on the hatch fits into a space just behind the rear seats, if you need to stow something tall but don't need to take the seats down. I have also been known to put the upper deck in next to an upright seat, forming a wall between the cargo half and the seat half, if I'm carrying a passenger and some larger cargo.
The heating and cooling system never turns off. Your fan just blows the vent air into the car, temperature of said vent air is controlled by the hot/cold dial. This means if you have it set to full heat and fan off, there's still a trickle of hot air blowing in around your feet, which can be uncomfortable, likewise if it's set to cold. The trick, then, is to turn the dial straight up if you want "room temperature" air, or move it around some to control the temp you want. Turning the fan on to one of the lower settings will get you that air moving around faster, but won't actually change the temperature of the air. The high setting is much much faster than the other three settings, but also much louder.
The AC button controls the compressor, which helps make air colder, but also dryer. The "defrost" settings also turn on the compressor, mostly because of the drying effect. You can run the fan all day and all night and you will probably never be able to detect the slightest effect on your mpg, and similarly it doesn't matter whether you have the dial at hot, cold, or anywhere in between. The compressor, on the other hand, saps some power, and has a small but noticable effect on mpg. Maybe as much as 5 hp and 5 mpg, probably less, but reports vary. So, when your windshield stops being foggy, turn the air back away from defrost. If you don't need AC, try turning it off and just run cool and fan.
If your heater isn't heating, either at all, or just at stops, you probably have low fluid in your coolant system. If this happens again after you fill it back up, you probably have a leak or a faulty water pump or something. When full, the heat on the Sonic is actually fairly impressive, if that's not your experience there's probably an issue.
