Prostar a/c issue

I recently replaced my dryer and condensor added freyon and everything is blowing nice and cold.. only issue is the a/c is blowing out the defrost and trinkles out the reg a/c vents.. the guys who installed the condenser and stuff said he thinks it's my climate control unit not changing it over to a/c.. before I ware $300 has anyone gone threw this ? Should I buy the climate control head? Thanks

 

How do I tell if it's the actuator ? Thanks

We were playing with the a/c and defrost knob and we had to play with it back and forth a few times for the door to close in that vent under the hood

 

I found my actuator none of the gears are spinning when I change the knob.. is it a bad actuator or the climate control box.

 

The actuator is located near firewall right? So when I turn the controls that spins around stops then if I change controls again it doesnt spin anymore
