Yardworks stuck chute control

My snowblower has slowly developped a problem with the chute control. It would get stuck and I would have to play around with the chute control stick to get it unstuck. Problem is that now it is almost completely stuck. I have looked at exploded views, but I don't know where to start. I have never played with this.
