I have had my snes controllers for about 3-4 months now. I have 4 controllers. One of my controller's L button does not get pressed down. It's not like the button presses down and doesn't register but it just doesn't press down. Does anybody know how to fix this or do I need to get a new controller? Please help me, Thank you :)

hm did u check the button maybe a piece of dirt or something blocks it does it not move at all and is it an original controller or a remake ?

It is an original controller and this problem has happened before but I just shook the controller and it got fixed but this time it will not get fixed. I will take the controller apart right now to see what happens.
