if its like the 8th gen you will need to remove the door sash (if you open the door it will be the plastic on the outside on the most rear part of the door running from the top to the bottom of the window) the screw will be on the inside part of the door towards the bottom. remove the screw and the sash should pop out a lil bit then you need to slide it up and off(this is of course if it is the same as the 8thgen, so check for any other screws). the damaged piece's end will be exposed where you should be able to pry it straight up off the door. the tricky part is under where it goes behind the mirror. removing the mirror is easier but you could just slide it out from there albeit it will be tough to do. hope this helps man!
