use this video, this is how i took off my door panels to get to the backside.
it is the same as the 2010, not exactly but just use your common sense to find the right screws...but once you get the screws out ur door should pop out....
in simple terms your door is being held on my two screws on ur door and the rest are clips that you just pop out by applying force to the panel, and unplug the controls on ur arm rest and ur good.
