I fixed it myself. Since I could not find any guides on the innards of the shoulder buttons, I decided to see what's up with it myself. I opened them both up, discovered that the nub that presses down the inner button wasn't reaching the inner button for some odd reason. So I cut a little tiny piece off of a birthday card and put it underneath the inner button to push it up. Now when I press the R button, I have to press down pretty hard for it to react, but at least it works! Also, warning to those who want to open the shoulder buttons up, the springs are VERY bouncy and there is one nut per shoulder button that can fall out very easily so be careful! It is a PAIN to put the shoulder buttons back in.
