the hot/cold blend knob seems to allow a door to flap shut inside heater unit. I can not find info in manual to help. Can you help?

The hot/cold blend knob, when it gets about half way, it kinda just flops over and no air will come out at floor. The air will blow cold to defrosters and other locations, but not through heater core to floor. Something is blocking air flow. Maybe a mouse nest. Fan works, heater core works, just no air flow. Is there an easy way to look in there and clean out whatever is there? Thank you in advance

If you have an air flow problem, the first question I would ask is do you have problems with mice? They may have built a nest in there. I have seen it before. It may be the fan motor and/or thermostat needs changing. Check your fuses. Check the coolant too.

Could be a hearer core problem. Hyundai's are simple and like you mentioned a flap does in fact open and close but still requires a working thermostat. That would be my first check as they are inexpensive and easy to change compared to a heater core. Thermostats sometimes get stuck with rust or minerals preventing the free flow of the hot water.

Make sure first that you have coolant in the vehicle and is you do and you seem like you are sure that the blend door is moving trying a new thermostat would be a good start if no good comes of that and you do not have leaks i suggest having the heater core and cooling system flushed to get ride of any build up that may be built up

the heat is produced by flow off of a part called a heater core. if this heater core that acts sort of like a radiator breaks you will loose the heat. This is best found if the air is blowing, but not hot. Sounds like a bad heater core. A good place to start is
