I need to get to the air blend door motor. What are the steps to take?

What is your question?

I have removed the glove box, and the motor is visible, but not accessible. I think that if the radio and that lower portion of the dash board is removed, I will be able to get to the motor. I do not see any screws that secure the radio or holes (like a Ford radio) in it for a special extractor tool. Also, I do not see how to remove the trim piece that surround the radio and air control knobs. How are these parts removed?
