Theres a problem with the valve that opens the heater hoses coming in. Not sure if theres a vacuum motor, electrical motor or just a cable controling the valve try to track it down from the face of the dash back. Could be just a slipped cable.

The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.When the Check Engine light (or Service Engine Soon or small picture of an engine) is turned on, the systems computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible system faults (the gas cap is just one of them) that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen/Oriley and Autozone parts stores (USA only) do this testing for free. I caution you on accepting any advice on what the problem is from a parts counter person, they are not trained and could cost you allot of hard earned money. Once you have the fault code post it here and I or another expert will take a look at the possiable casues.

So have the Evap System tested

It depends on what type of vehicle you have. Some vehicle have electric air distribution, if this is your case, you may have an electric duct motor not working due to burned motor or not receiving electricity from the control bottom. If your car doesn't have an electric air distribution system, you have a loose cable behind the dashboard.

Pull the dash and replace the blend door and the blend door stepper motor.

Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.
