How do you fix jamed a x y b buttons

Hey, Jack. Does depressing the button physically feel “jammed” or is it just taking a lot of pressure for the button to work? If the button feels stiff something is probably bound up or it has some kind of debris in it and you’ll need to take it apart to see what it is/clean it out. As far as the button hardly working, the conductive pad on the back of the rubber could be dirty or worn out. Try cleaning that conductive pad (its the little dark grey dot on the back of the rubber piece, I’m including a picture below) with IPA or adding a touch of conductive paint. Hope this helped. Good luck.
