To determine the direction of air flow in an AC unit, you can hold a tissue or a lightweight piece of paper near the vents. The direction the paper moves will indicate the direction of the air flow.

Yes, air flows from hot to cold.
Air flows from areas of high pressure to areas of low pressure.
Determine what is not working properly, then determine why.
The unit for air resistance is Newtons (N), which measures the force exerted by air on an object in the opposite direction of its motion.
You can determine wind direction by wetting your finger and holding it up in the air and feeling which side of your finger is being hit by the air. This would mean that the wind is coming from that direction.
You look in the maual!
by latitude and is affected by the movement of earths air

The force of air typically flows from areas of high pressure to areas of low pressure. This movement creates wind and air currents.
Without seeing the unit it`s hard to say with absolute certainty but most are air out.
remove engine cover. locate AIR MASS unit ( unit where fuel enters your engine-- -drivers side where air also flows into engine) the EGR valve is located right in front of AIR MASS unit. good luck
