I have the exact same problem on passenger side but no luck fixing it either. Just hoping there might be a chance of a solution now having been about a year since this was originally posted. It's happened previously but we were always able to set the latch back to unlocked position by using a finger of screwdriver to flick it back. Now it won't do it and not sure if it's the plastic that's jamming it. It doesn't seem to be. Is there a way to reset it?
Just hoping there's a simpler solution than replacing the part.
