Support is an independent issue from visitation. If you want to enforce the visitation orders, then you'll have to go to court to push that. The judge isn't going to say, so the kid doesn't want to see you, fine don't pay. The payment doesn't go to the kid, it goes to the mother to defray the care of the kid.
Teenagers often don't want to do the visitation (cuts into their "busy" schedule), but if it's important to you, the other parent should compel it.
