A/C Vent issues
 

So i have a 94 318i and on the climate controls, dial controls, not digital, when i turn to arrow to the head position for the vents the air comes out cold with the a/c on, but when i turn the dial to have the a/c be directed to the feet or the windshield the air comes out hot even with the a/c on but then when you turn it back to the head position its cold air, what the heck is going on here? Thanks

anybody?

Any remote ideas was to whats wrong or needs to be fixed?

Well, I think nothing is wrong. My car has the same symptom, but I have a separate temperature control for head air flow just under the central head air vent (it's similar with the on/off control of the central head air vent, but it has red and blue colors on it). And the head air vent is what I suppose to be "ventilation", which don't take in consideration the temperature control from A/C & heating controls, but only this horizontal rottary wheel with red & blue.
And is possible to have hot air on your feet, with cold air on your head - this keeps me awaken when I'm tired & driving.
