My 06 did the exact same thing. The heater door opening up to the floor was broke. I hope in your case thats not the problem, mine carried a 2400 dollar fix. Had to remove the dash all the way to the firewall and replace the broken door. Dodge knows they have a problem, because they offer a repair kit ready to go. Mine went out at 65000 miles and just went out again last week at 120,000 miles. This time I'm buying a big blanket for my feet, cheaper than a fix. You could be the lucky one and it might be the motor that opens the door, your local good mechanic can check this with a guage to see if the motor is operating properly. If not, I'm afraid yours is like mine. Mine was acting just like yours, all the heat above nothing below, Good Luck.
