How do you get your L or R button working again on the GameCube controller

If they arn't working AT ALL, then you may have to just buy a new controller. If you don't have the money, or just don't want to buy a new one. Then i would say, find a safe way to take the controller apart (DO THIS ONLY IF YOU CAN PUT IT BACK TOGETHER!) If they are sticking and you cant get them unstuck, then i usually just spit on it or lightly throw the controller lol. As disgusting and stupid as it sounds, it can sometimes work. I would recommend just buying a new controller though since it is less trouble and the issue probably can't be repaired without an engineer of some sort. Hope this helped, even if just a little! =)
