You may have a problem or bad connection in the a/c-heat control unit I'd remove that and inspect that first. As long as you do have heat elsewhere you can rule out the blend door actuator. There are vents that open and close and you will need to be able to access and check them. You will need to remove dash to be able to get to them.

Your vehicle uses electronically controlled blend doors to direct th air flow from defrost to vent and to the floor . If the door motor is bad then it will stay at a fixed position so you will not get the air to flow out the defrost ducts. There are at least two of these one for air blend and one for fresh air. They are located on the passenger side usually under the plastic cover and have a wire harness that plug in and are usually shaped like a piece of pie.

Floor vents not working in my Avalon.


When you turn the dial to the floor vents, do you hear anything. You should hear a flap or something move after the dials been turned. There's a flap (direction control) just above the blower behind the passenger side dash. This directs the air to where it's supposed to go. It sounds like yours may have come loose

if your ac is on max i believe it recirculates the air in the car by sucking air in by the defrost vents and blows it back out of the normal vents try to move the controls to make sure the that the shutters are working and make sure the ac is not on max by selecting the knob that has an arrow going through the little car instead of the circular one that might fix the problem
