Passenger window won't work

[Curly94]

My passenger window has been fine since I got the car and was working fine till I was out the other day, my door was slammed (unsure if this could cause it?) but it the made a rattle like something was falling inside the door? Happened to be a very wet day but manage slide it up till it was almost closed but the next day it was really heavy rain to the extent of flooding and to save the inside of the car someone pulled the window up with force to close it resulting in more rating in the door while it was being done, any idea what caused it and what's needed to fix it?
