    Do you have a Circle Pad Pro? That thing has an extra R button IIRC.

    If you can get a better screwdriver so you're able to open the console it's pretty easy to repair or replace the shoulder buttons. You can usually fix them by removing the little rubber piece and cleaning inside the switch with isopropyl alcohol and a toothbrush. Otherwise, you can replace it cheaply.

    Even if you can't open the console, you might have some limited success using a toothbrush and scrubbing around the R button from the exterior after dipping the brush in some alcohol. If the bristles are flexible enough to fit through the gaps in the housing they might make it inside and transfer some of the alcohol to the switch for the R-button, which may be good enough to dislodge any dirt in there and improve responsiveness.

    If the contacts inside the switch are oxidized, there isn't much you could achieve by blowing into it other than making it worse.


    Youtube video shows you how to open it up and take out the L/R button switches. Judging by how they looked, I think you might be able to open the triggers up in a similar manner to the DS Lite's triggers. That should allow you to take out the rubber button and the metal cap inside the switch, so you can clean them out.

    As always, when opening up electronics, don't force anything open; be careful. I am not responsible for anything if you broke something from being too rough :P

    That being said, your R button already isn't really working, so even if you broke the trigger, it already wasn't working in the first place.

    Otherwise, if you are interested, you can get replacements for cheap here: http://www.amazon.com/Internal-Shoulder-Nintendo-3DS-replacement-packaging/dp/B00C9CBH5E

    Thankfully, for the 3DS, the L/R buttons are on cables that connect to the main board, rather than triggers soldered directly onto the motherboard :P that makes it much easier to replace them.
