This happened to me a few years ago, and the little clip was still available from Merlin at the time. I seem to remember that the clip I needed to replace was purple in color. Of course my mind is like a rusted steel trap now and I might be mis-remembering. I would need to see the mechanism in place to say what needs to be replaced. If you have the time I was planning on removing my door panel tonight anyway, and I could take a picture of what's going on in there for you.
