Stuck heater box door causes no heat from vents?

Heat wont blow through heater or defroster vents.
Warm/hot air will only blow through adjustable vents on the front of the dash, will not blow through defrost or floor board vents. However, cold air (from air conditioner) will blow through all vents - including upper dash defrost vent.

Got it to the mechanic
The door in the heater box was stuck. It is located under the dash on the passenger side. Repairing that stuck door solved the problem.

Same problem faced again
This time changed the gas cap and got heat all around. something about pressure.
