To answer your question, it depends what is wrong. They might not just be stuck.
The sensors or their wiring could be bad.
The vacuum motors or their vacuum lines/source could be bad.

Might try a seafoam treatment just for the heck of it tho.

Good luck and let us know.

My buddy Randy recommended two other things.

"Sometimes the clip for the arm just falls off. You can feel it if you put your hand on the control
Another thing I've seen happen is when someone will do an induction service and instead of cleaning all the gum out, it softens it and makes it real sticky and causes the flaps to stick in the manifold."

Good luck.
