"Why can't I switch my ventilation to anything but dash vents?"

At first the a/c would not turn on and cool although the button had been depressed and amber light was on. Checked freon and compressor. Charge is good and compressor running. A month later started having trouble with ventilation choice. Every once in a while it would hang up on one setting or the other. Now it is permently stuck on dash vents and can not switch to defrost or floor. I've been told 2 different possibilities. One was a part in or under dash that is malfunctioning and entire dash would have to be pulled. The second is that it has to do with the function switches and that an electronic component that they are attached to is bad. Any thoughts appreciated, no defrost in winter not a good thing!
