Air conditioner unit gets no power

My air conditioner control panel started not working correctly. You could not use buttons on center dash, only turn fan and temperature up by the steering wheel controls. It was coming on automatically when cranking the vehicle and after driving ten minutes or so the power button was the only button that would work. No way to control which vent or turn on rear defrost. A few days later, no power at all to the center console for the air conditioner controls. Radio does come on and works. Which fuses should I check or any suggestions?
