it is 100% door carrier assembly. You can buy it for $90 approximately from a dealership and then if you want to do a DIY then it is not at all a big deal. I did it for the exact same reason. First time it will take you littl etime as you have to figure out where the nuts are. Open the inside door panel completely and then take the door handle out and you should be able to install carrier assembly.
