Well, a bit of an update. After looking at a few guides to taking Wii remotes apart on the Internet, I've decided that it's probably not worth the hassle. I don't have an air can, Rubang, but I did try blowing into it *really* hard. Unfortunately, no go. I even tried scraping the insides with an IC extractor, but that just ended up scratching the remote.
Thanks everyone for their help. I was hoping there'd be a simple solution (like the one for a malfunctioning motion sensor). I'm going to buy a new Wii remote to replace it and keep the old one around as a spare.
@windbane: I've mainly be playing Star Soldier R with it. It is possible that I may have pressed to hard on it at times, but I thought Nintendo controllers were practically bulletproof.
