What do I need to fix my Joy Con Directional Buttons?
A few months back, I had been gifted a used pair of neon Joy Cons. They look great, but the left (blue) JC needs some work. Previously, the left directional button was only partially responsive, working maybe 1-out-of-5 times I needed it to. After using a soft bristle toothbrush and some WD-40 Electronic Contact Cleaner to try to clean around the button and inside the recess, it has now become completely nonresponsive. If the rest of the joy con is functioning normally, what components (not including tools, which I have) will I need to fix this myself? I don’t want to have the wrong parts, nor do I want to be missing parts I’ll need.
