Introduction
If your trigger buttons for the Wii U gamepad aren't working as intended, broken, worn, stuck or create unwanted noise, you can use this guide to replace the ZL and ZR triggers of your gamepad. The process will follow six easy steps and it is very beginner-friendly.
The gamepad will be screwed open and some wires will be temporarily disconnected to gain access to the trigger buttons. The gamepad will require one special tool to be opened so refer to the tools section to make sure you are ready.
Before starting, make sure your Wii U gamepad is powered off and disconnected from any wires.
