Had this issue with my DSi's R button. Blowing into it worked for me, for a little while.
All these fixes seem pretty temporary, wish I knew a surefire way to get in there and solder or replace something to get some peace of mind.
Anything and everything about retro and modern console repair.
If you've got a broken gaming console you are trying to fix, come here to talk about it. If you want to flex about a repair, post here. If you or your console's last lover did a non-destructive electronic mod to their console, or have a question about the options available or how to do it, you are welcome to post here.
If you suck at soldering, we still love you, but we might roast you.
If you did an extreme modification such as turning one of the few Nintendo Playstations into a Rubik's Cube, flex elsewhere. If you're trying to FIX a Nintendo Playstation that someone turned into a Rubik's Cube, post away!

Don't blow into it. That introduces moisture, and moisture can worsen microcorrosion.
The best way to fix it is to take the back off, pull the plastic buttons out, and spray contact cleaner directly into the tiny seam surrounding the switch. Then, rapidly press the switches repeatedly.
I've fixed a few dozen DS L/R buttons like this. Unlike blowing into it, contact cleaner keeps it working for a long time.
