the same thing happened to the passenger side of the TD. As I recall if you look at if closely (and look at your passenger door) there is a self tapping screw that goes from the inside of the door into the trim piece, which in your case in no longer there. You will not be able to replace this screw as the trim is 'stripped'. I drilled a small hole through the outside of the trim and put a small 3-4 mm screw from the outside to the inside with a flat nut.
I just tried to take a pic, but it is too dark out and you can't see anything in it, sorry. I think if you look closely at the pass door, you'll figure it out.
