Are you saying that the NORM position works properly, that you get cool air thru the dashboard vents when you select NORM? But when you select MAX, the cool air blows onto the floor?

The FSM describes in quite a lot of detail what colour vacuum line operates what flap/door for your heating, cooling and vent arrangement. Pretty good bet that there is a problem in one of those vacuum circuits.
