This piece fell off when someone took my door trim off. He has no idea what it is or where it came from. I've taken the door trim off many times, and have never noticed it before. I took the passenger side off and can't see a matching piece, which leads me to think it might be something to do with the driver side door lock nozzle, but its not obvious where it goes.
Everything seems to function fine without it.
Anyone got any ideas?
