Having run into this issue quite a few times over the years, your problem is most likely in the button membrane just underneath the button it's self and/or the contacts under the membrane on the system board. I have seen carbon build up on the contacts causing the button to malfunction. My suggestion for you is to purchase a new membrane for your 3DS and then clean the contacts underneath the membrane with rubbing alcohol and then using a pencil eraser, clean the contacts after the alcohol has dried. Then reassemble the 3DS.
