everything works fine when its on the floor mode also the cooling fan for the engine does not come on
I can't offer specifics, but this thought - relationship came to mind:
The air directional controls are vacuum operated - and the engine will run real rough and like to stall when there is a vacuum leak.
The heater directional vacuum control is on the firewall - somewhere above the gas pedal. Look in this area, both inside the car and in the engine compartment for disconnected/broken hose - and especially anything that is hissing like a mad snake.

Check behind the heat control panel to be sure that the vacuum hoses are all securely plugged into the control switch. As a safety measure on all cars, if you lose vacuum altogether, the default position for air direction is on defrost, so you can always see out of the windshield. Jake McCahn

The heater control valve in a Mustang is located within the engine. It is right in the heater's core and where the coolant is located.
