Okay, that sounds like a floor/panel mode door controller failure. Not a hard repair but lets try a re-calibration first. Go to the smart junction box and remove fuses 10 and 12, leave them out for a couple minutes. Now turn on the key. Wait about forty five seconds. Turn off key. Reinstall the fuses turn key on again, wait thirty seconds or so and test the controls and see if it now works. If not then you need to remove the lower trim panel and cover under the dash on the drivers side. The control motor is midway up the HVAC case.
