Either the A/C Panel Mode Door Actuator which is vacuum run or the HVAC Heater Blend Door Actuator which is electrically run.

i dont think its a temp problem with the question they asked...> Blend Door A blend door is mounted within the heating and air conditioning system and pivots to divert warm or cool air into different passages within the system to keep the passenger area at the desired temperature. When a vehicle is cold, you may desire maximum heat to enter the passenger compartment. In this case, the blend door may be moved to divert all of the heated air into the cabin. Once the vehicle warms up, the blend door may be moved to divert only part of the heated air into the cabin. When cool air is desired, a blend door is closes so that no heat enters the passenger area. Blend doors move by way of a mechanical device referred to as an actuator. Blend Door Actuator In some automobiles made prior to the 1980s, the blend door may have been actuated by a metal cable that was connected directly to the temperature control lever on the dashboard. A sure way to move the blend door, some systems took more than a little effort to operate. As autos had more and more labor- saving devices added as standard equipment, heater and air conditioning controls could be operated with less effort when automakers started installing blend door actuators. An actuator moves the blend door automatically when the temperature control is moved. An actuator can be powered by vacuum or by a small motor mounted within the heat and air assembly.

So the HVAC Actuator or the blend door itself is stuck at the vent & floor setting. I think the terminology (description) of this part is deceiving as this is what this part is called in my truck that I had to replace in order to make my defrost, vents, floor air flow to work. Yes not a temp. problem.
