window came off the U shaped bracket. It seems that it's only attached by silicone, Any one else have this problem.
it happens all the time on the older Expeditions and F-150s. it is basically held in with silicone but its more of an epoxy. you have two options well maybe three. buy a new window because it will have the bracket glued on it, two have a window repair shop reglue it for you, or three see if a auto repair store like NAPA has a glue or apoxy for windows. it may even be glue for installing windshields. Make sure you clean all of the glue out of the bracket and off of the window apply new glue and reassemble making sure to keep your window up for a couple of days until the glue sets up. Silicone will work for about three days so thats not the fix.
