A stuck temperature blend door, or the temperature blend door actuator went bad (most likely). You feel the heat coming from the heater core as it is always "on," (it works like a mini radiator), some air movement through the vents allows some heat to reach your cabin, but as long as the temp blend door can't open to the heater core side, you won't get any heat. Google how to replace a blend door actuator for your make and model.
