The air con mode control is vacuum powered. There is a small hose that connects to the back of the inlet manifold top plenum. If there is no vacuum then it will be stuck on demist - like yours is. I had that exact problem and found that the line had fallen off the inlet manifold. I put it back on and the control worked again.
