backpart
It's not hard AT ALL! I just did mine twice (bought a cheap imitation one on accident on eBay and it broke right away). Just pull out the backpart of the handle on the door...pull up on the rest of the handle/the window controls, take off the two screws from the bottom of the panel, take out the three bolts that were hidden under the handle and window control plate, slowly work a flathead screwdriver around the panel and pull up (don't break it...you're just trying to get the tabs out of the holes under there one at a time which may take some force but just be careful), then pull it up and off careful to remove the wiring from beneath and the door lock which just unhooks...then you can just pull up on the tabs that hold the knob in place...take the unit out and replace it all .
