I found it. My dad happened to have a little multi tool with a phillips head on it and I got the door off and found the broken plastic piece. I was able to get the plastic piece reattached to the door and the metal rod back into it, but it's only a temporary fix as I'm sure it will fall out again soon with only half the plastic still there. I will probably go ahead and order a new set of two and wait for the other door piece to break!
