In this case, you are most likely looking for a vacuum leak. The vent doors that direct the air are actuated by vacuum. Check under the dash for leaks, damaged hoses, or disconnected hoses to the system. NOTE: With the engine running, you may actually be able to hear a hissing sound where the leak is coming from.
Let me know what you find or if you have other questions.

Well I found the problem. On the driver side floor on the top right side their is a white lever. That white lever has something attached to it and that is the part that broke. When I move that lever up and down it will turn the defrost vents on or off. But what is the part that I will need to reconnect that lever back up.

The part that I need is the mode door actuator lever assembly parts. Now all I have to do is find who sells these parts so I can buy them.

That is going to be a dealer part or you can get one from a salvage yard. I feel confident you'll find one in a salvage yard, and it will save you some money.
Let me know if you can't find one.

I had a similar problem I had heat only on one side of the vents It was actuator assembly and it comes all one peice which works alot of diferent vents and plus vacume it is a dealer item plus most likely a dealer job the entire dash needs to be removed to change this actuator where I live the dealer charged $800.00 bucks it was 8 to 10 hour job. Sorry good luck

Actutally I found a diagram on how to change this part and it is very simple just a few minor lever assembly parts that need to be put back in place. The dealers always charge outragious amounts when I called a dealer to ask about the problem the first they said it was a blend door and that the price was about 1200 when I told him it wasn't a hot cold issue and stated some facts he said oh yah that part is part of the mode door and asked I if I wanted to make a appointment I stated no thanks bye.
