I just had the same problem with my driver side power window. My window also slide down and sounds like everything was broken. I finally manually retrieved the window glass and put tape to hold it up so it would not fall and break the glass. Sounds as if all of the inside of the door is broken. Is this a defect because nothing was done for this to happen. I also have a 2008 T&C and have never had a problem like this.
No it is not a defect , your vehicle is 7 years old and things break. Call a couple of body shops and a couple of auto glass places to find someone to fix it.
