Duenevw: WELCOME TO THE BOARD!
Although you did repair some critical parts of the system here is what I think:
A. If air is blowing from the wrong vent (when not selected) then it signals a stepper motors problem and possible the control unit. AKA sword though you did relace but did you test it ?
B. If heat is blowing instead of the outside air then it points towards the heater valves being stuck open.
C. Also I would suggest a heater control simple test. Light comes on when you push the buttons, electronic switches AC light. In your case a dial knob does your fan work in all three speeds?
Hope this will help
