door glass came loose from window regulator
are you sure? most likely the window regulator failed or a cable broke.
Sometimes the door glass can reglued into the window channel.
If not, then the door glass has to be replaced.
yep, had this happen on a friends car. There was bolts to help clamp the regulator to the window, but the “cushion” around the clamps had dried out. Put some new foam in there and tightened the clamps back down. Still working well, as far as I know.
Yep had the same problem with my Dodge truck and used the same fix and still working after 10 years.
