Anyone know what the black plastic door hinge on the front doors does? It's obviously not the main door hinges which are metal and this is a flimsy plastic . It connects in the center of both metal door hinges and goes behind the door . Whatever it connects to, it's making a clicking sound all of a sudden when I open or close the passenger side door and I can also hear it click going over bumps. Super annoying and I haven't had a chance to pull off the door panel to see what's going on behind it. Just curious if anyone knows offhand before I have time to rip into it.
