Default heat/ac problems. maybe blend door?

Hi folks, new to this forum stuff so bare with me. I have a 2006 Sonata with the auto climate control system and in the past coulpe months been having issues with no heat in the car. Now its becoming an issue due to temp drops at night and needeing to defrost windshield in the morning. the defroster works but it will not blow warm air at all. comes out ice cold. Heater hoses are both getting hot and its full of antifreeze. Any ideas? Thanks

Having same problem with heater on 07 Sonata SE. Out of warranty can anyone help? Heater Blend door actuator is moving when temp control is changed. There is temp difference on the in and out hoses so water is flowing. How do I check to see if Bend door is actually moving with actuator? What else will cause it to blow only cold air? Any and all help is truly appreciated!

Mine ended up being the blend door actuator. Wish I could've taken it back to the dealer. Way out of warranty. Thanks for that helpful reply. Sometimes now the actuator won't move when I change the temp and I'll have to turn the temp **** back and forth a few times to get the temp to change but at least i get heat now.
