Heat blows from vents but won't blow from floor when put on floor mode

You most likely have an air door actuator problem. It's stuck in the vent position and can't shift to the floor position. The two doors that governs flow between dash vents and defrost/floor are "mode door 1" and "mode door 2." Mode Door 1: This door regulates air flow to either the dash vents or defrost/floor. If you have air flowing only through the vents with no defrost or floor, this door is failing. Mode Door 2: When mode door 1 is set to divert air away from the vents and into the second stage of the system, door #2 chooses whether air goes to the defrost vents to the windshield or out through the floor vents in the passenger and driver’s side footwells. Failure is indicated by an inability to choose between defrost and floor. There is an excellent write-up on these doors and how to replace here: http://www.heatertreater.net/Ram%2002-08%20Listing.html

i hve a 2003 dodge ram 1500 and blower fan is stuck to one vent. The control knob just turns freely and does nothing what can I do to fix it

No heat on the floor turned out to be a broken actuator coupler. Not the actuator itself. It’s what the actuator slides into that moves the blend door. No idea where to find this piece or what the part number is.
