Mazda Repair: Low heat on drivers side, mazda mpv, 2003 mazda mpv

Question
I own a 2003 Mazda MPV mini van and the heat that comes from dash and floor are great on the passengers side but low and not as warm on the driver's side.  How do I improve the air flow and heat on my driver's side?

Answer
it's normal in most cars to do this because the blower motor is normally lovated closer to the passenger off center. other then the ducking being blocked i'm not to sure what it could be you can also try changing the cabin air filter might not help but it is always a good idea.
