Chosen Solution

I took apart my pro controller today to change the right joystick. When I took the motherboard out I have a little clear piece and a little black piece that I can’t figure out where they belong to put the controller back together. I think they go somewhere around the mount for the charge port but I’m not sure any help would be appreciated. I got curious and removed everything from the controller and got myself into a predicament.

Hi! I haven’t taken one apart, so I can’t tell you exactly what you’re looking at. However, I did find this Replacement Guide that might have a photo of the area inside the controller that your spare parts should end up. Nintendo Switch Pro Controller Joystick Module Replacement
