Does it ever switch any other way like from floor to dash (bottom to top)? Kinda sounds like a faulty mode door actuator, the little electric motor that controls where a door is positioned, thus where the air flows.
I bought a can of freon at supermart. It had dye, oil, and stop leak in it. It also came with a hose and a gauge. Now I'm an ac professional!!!

Hey Williamkoch, Could the temperature have been set at a point that would have caused this? I think you are hitting the wrong mode button which seems to have activated the automatic changes. If you still face the problem, then check this out for more help.
