What do I need to fix my Joy Con Directional Buttons?

Hey @daewok!

It sounds like you could have one of two problems:

1. The left button contact is bad (or has something stuck to it). In this case, you would just need to replace the button itself—you can find sets on Ebay or Amazon for pretty cheap, and follow this guide for the repair.
2. The contact pad on the motherboard could also be bad, in which case you would need to replace the whole board (which is also pretty cheap on Ebay). We don’t have a specific guide for a motherboard replacement yet, but the steps are the same as shown in the button removal guide.

The Joy-Cons are actually pretty easy to work on, as long as you’re careful and stay organized! I hope this helps, let us know how it goes and if you have any more questions.
