my latio aircon is behaving quite funny recently ...
sometimes when i start the aircon , blowing direction is from bottom ... 
the day b4 i remember i didnt change any settings of the blowing direction.
this problem is occasionally ... happen like once per week..
another problem i encounter is the temp sensor ...
seems like hay wire liao... yesterday i check once its 43DegC !!
something wrong with the temp sensor liao ??
temp sensor is inside cabin rite?
There is nothing wrong with the blowing direction. Your aircon must be set at auto, when in auto mode, the aircon sensors inside the car will try to achieve the temp that you had set, and same time the different sensors inside the car will direct the air flow to blow at different places, to achieve maximum comfort for the passengers in the shortest possible time. This feature is very useful in countries with four seasons, where hot/cold air blowing thru ducts at the deskboard or feets, not only directly at passengers.
Your aircon will automatically change the air flow back to directing at passengers once it reach certain temp. You can deactivate this feature by turning to manual. In maunal mode, the air flow will not slow down even the aircon has reached the temp you had set.
I agreed the temp sensor for outside is not accurate. I have the same problem. I believe is the placement of the sensor, must be too near to the heat source - engine bay, exhaust, facing the road surface or even the car metal body that indirectly transfer the heat to the sensor. Need to talk to TCM to understand where the sensor is located to conclude whether the sensor is faulty.
