Too much hot air on windsheild makes driver uncomfortably hot regardless of control position. What could cause the excessive air flow across windshield

If you cannot prevent the airflow from blowing on the windshield (defrost setting) by changing the settings then there is likely a fault with the A/C and heater control system. You'll have to have it checked out to know where the fault lies.
