Question 86 gmc Defroster problem??

My defroster is not working.The Heater works good, but when i switch to defrost it still only comes out of the vents. I can manualy move the door by the lever and it will work.I dont know if im missing something or something with the vacuum but i cant get back to see with out taking my whole dash apart why its not opening by itself.
