Hi Customer (name blocked for privacy),
I'm happy to say that I think this is an easy fix. I've included a diagram to easily identify what your talking about. I believe your talking about part #2. If so it's a 3-5 dollar part. If this isn't what your talking about let me know and I'll try my best. If I can't help you I'll gladly opt out and let another Expert help you.
