This happens when the temperature blend door actuator goes out. Here is the location so you can change it out. Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed.

Thank you very much for the quick reply. Two things: do I need to take glove box out to reach it? And can I adjust the blend door manually before I get the new part?

Taking the glove box out should make the job easier for sure but they do not say how to calibrate the actuator, I have seen people remove the battery cable overnight which can help the system reboot and recalibrate as part of the HVAC initialization process.

Because I have a conflicting issue with the correct temperature actuator (different part numbers between Hyundai OEM Part #, e-bay Part # and Amazon Part #) I would like to take out the bad actuator and try to manually turn the actual door left+right to find out if doing so I will have heat in the car because as I said previously all vents work properly but the pump blows only cold air. The problem that I have is I do not have a clear picture of the location of that actuator and if you don't mind please instruct me where exactly the location of the part is.

Yep, it is on the passenger side near the center console. You will need to remove the glove box and lower panel to get at it. If you upload pictures of anything you have a question about, I can walk you through it.

Thanks for your reply. As I said before about the conflict part numbers from different manufacturers, I was right that none of these parts were the right ones. So, I took it out and I found out the exact replacement part. 4 seasons HVAC heater blend door actuator # 73371 from Carid. Com, $ 64.00 with free shiping (also Bay $70.00 to $84.00, Parts geek $61.00 + shipping) It fits only old body style models. It's located on the left side of the bottom of the heater box. There is an electrical connector visible and 3 screws. Unplug the connector and remove three screws, the unit comes down and you expose a metal bracket (panel). You can use your finger to move the bracket in or out and that changes the position of the blend door that brings hot or cold air into the cabin. If you don't mind the pain of removing the old part from the bottom of the heater box with a mirror you don't really need to remove the glove box. On the other hand, if you remove the glove box you have better visibility and also you have the chance to replace the cabin air filter. If you replace the part be sure that the metal rod on the plastic bracket fits inside the groove of the exposed metal plate. Connect the electrical plug and start the car, let it warm up and use the temperature knob in your dash panel to change cold air to hot air inside the car. That actuator controls only the temperature not the direction of the air to the vents. If that is the problem, then this is a different animal, and you will need to find out the right actuator ( I believe it is the blend door mode actuator) and the location of it in the HVAC system. Thank you again for your help.
