Installation Instructions
This section outlines the steps required to replace the SL/SR button flex cable in your Nintendo Switch Joy-Con. Exercise caution and precision throughout the process, as internal components are delicate.
- Step 1: Open the Joy-Con Casing
Using the included "Y" (Tri-Wing) screwdriver, carefully remove the screws located on the back of the Joy-Con controller. - Step 2: Remove the Internal Battery
Once the back casing is open, carefully disconnect and remove the internal battery. This provides access to the internal components. - Step 3: Remove the Original Button Flex Cable
Using the included "+" (Phillips) screwdriver, remove any screws securing the old flex cable. Carefully detach the old flex cable from its connectors. Note the orientation of the original cable for correct installation of the new one. - Step 4: Install the New Button Flex Cable
Carefully position the new SL/SR button flex cable into place, ensuring it aligns correctly with the connectors. Secure it with the screws previously removed in Step 3. Reconnect the battery and close the Joy-Con casing, securing it with the "Y" screwdriver.

Operating the Repaired Joy-Con
After successful installation, the SL and SR buttons on your Joy-Con controller should function as intended. Test all buttons and connectivity to ensure the repair was successful.
Maintenance
No specific maintenance is required for the flex cables themselves. To prolong the life of your Joy-Cons and internal components:
- Avoid dropping or subjecting the controllers to strong impacts.
- Keep controllers clean and free from dust and debris.
- Store in a dry environment away from extreme temperatures.
Troubleshooting
If the SL/SR buttons do not function correctly after installation, consider the following:
- Cable Connection: Ensure the flex cable is securely and correctly seated in its connectors. These connectors are very small and require precise alignment.
- Cable Damage: Inspect the new flex cable for any bends, tears, or damage that may have occurred during installation.
- Battery Reconnection: Verify that the Joy-Con battery is properly reconnected.
- Tooling: Some users find that specialized fine-tip tweezers are helpful for handling the delicate ribbon cables and connectors. While not included in this kit, they can aid in precise installation.
- Reassembly: Double-check that all screws are tightened appropriately, but do not overtighten to avoid stripping.
If issues persist, it is recommended to review the installation steps carefully or seek professional assistance.
