2005 forenza no air control just on upper defrost
 

Where do I look to possibly fix my air dampner for my defrost. Right it is just on top/defrost. It won't change to blow in our face or feet. Temp changes just not location. thx. 2005 wagon. Would like a schematic if anyone can provide one. I'm not real literate when comes to vehicles so diagrams do help. I just bought this car. That's one thing I would like to fix. I would also like to add cruise control. How much will that cost me to do. Parts and probably labor.
