I know I've got a loose connection in my drivers door (bottom window rear window rail) that I've got to get in there and weld tight,
My money is on that detail right there.
With the glass held tight in the fuzzy channels at the top and at the wing vent channel, but loose at the rear corner, a single hard slam of the door (by a greenhorn passenger) could crack the glass.
