Window Broken (REGULATOR IS FINE)

[BigWalmac]

Guys,

So my wife's X5 window is broken. All the symptoms of a window regulator problem. I bought a window regulator, took the door apart, went to install it and found the regulator is fine and still works well. On re-installation i saw that there is a piece of support metal that runs down the door. It holds the window lining/felt/insulation in place. (Essentially the window seal on the top, that runs down, past the front mirror, runs all the way down into the door and is welded to the bottom of the door) Well, the weld that holds that lining and support to the bottom of the door is broken. I think this maybe what causes the window to pop out of its alignment.

Anyone run into this problem? Anyone fix it? Weld it? metal glue? Suggestions?

Thanks,
