Now just pull the entire assembly toward the front of the car. There are clips that snug fit it to the weather stripping on the bottom rear edge. Pulling with a little force will free the assembly and let you move it away from the car. Remember these clips when reinstalling the assembly. It'll never fit right without those little guys in their right spot.
Now with this area open, go back to the driver's side and move the rubber downspout out of the way. Down here you'll see where much of the wiring enters the car. Don't worry - we're not scraping our hands up trying to get to that. We're going inside the car with a coat hanger to push through a free opening and grab it from inside the engine bay once it pushes through.
