Hi!!
The part is called Blend Door Actuator, it is located on the passenger side under dash, behind glove compartment, on the blower motor housing, is held by two or three screws and has an electrical connector plugged into it. You can get a replacement at almost any auto parts store.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

okay....thanks to you I know what part to ask for...any idea where to get an instruction diagram to install it?
Thanks again!
Its a pain to change you have to remove the dashboard cover including the glove box. Disconnect the passenger air bag and it is located behind there. Its a pain to do , since i have done it twice . The first time i did it i installed a used one. Dont bother getting a used one , most dealers can still order it and it is about 100 dollars. there you can get it on ebay as well just search for Ac/heat actuator. It is a pain to do.
Is that why the middle two A/C vents dont have any air blowing out of them but it comes out fine everywhere else? It also makes a weird humming noise under dash when A/C mode has the air coming out or the front vents alone. Is it because it is sending signal to open the flaps and they are not responding or is it just a noise from whatever is not working in the first place? This is a 2002 Lexus RX300

There is nothing that prevent air flow in the vehicle. There is a blend door that controls whether the air is hot or cold, a mode door that controls what vents the air comes out of, and a fresh air door that controls whether or not the air comes from outside the car or recirculates inside the car.
Is the blower motor working?
