Knob is stuck or it can move but the air flow is stuck on one position?

It can move but the air flow is stuck on one position.
It's blowing air out the front and I can turn the knob but it won't change which way the air is blowing. This is only really a problem when trying to defrost my windshield when it's cold outside as I've been having to drive with the windows down.

Check the intake door motor and linkage adjustment.
