climate control issuses

What is your question?

when i turn on my a/c or heater the air fluctuates from vents then to floor then to defrost and continues on like that i turn my knob to try and control were it comes from and it wont change it then at times it will just blow out of vents but i still can change it from there to any other place to blow out i bought new climate control installed and still same thing
