4 SNES Controller R bumper not responsive
I received a North American version of the Nintendo brand SNES controller where the right bumper does not respond. I opened it up and cleaned out all the contacts and I also can't find any sort of wire break or pin problem. I read that this may have to do with how the controller interacts with the CPU with pulse clock cycles, but other controllers I've tried don't have this issue. Is there any way to fix this problem, or am I stuck without a shoulder button to lean on?
Es esta una buena pregunta?

I have basically the same problem! I have had this SNES controller for a long time that's L-button is not working. So I took it apart today, cleaned all the parts and put it back together. But now the R-button doesn't work either! So all the other buttons work great, except L and R buttons. I have no idea what the problem is. I used a multimeter to determine that current gets through the connection when button is being pressed. I see no visible damage to the circuit board or wiring inside the controller. Is there anything I can do to fix this?

@czab do you have a short in the cord itself???

I got the R-button working so I guess there was just a poor connection. But the L-button doesn't work at all. After some dissecting and testing I came to the conclusion that whatever chip that processes the button inputs just doesn't respond to the L-button anymore. That isn't a huge problem since many of the games doesn't utilize the L and R-buttons anyways.
