Here's some information that you can use at your own discretion. Not responsible for any damage you may cause to your MDX etc.
This weekend, while cleaning my car I found a piece of plastic under the floor mat. it turns out that it is the piece of plastic that fits over the pivot of the rear wiper.
Further inspection indicated that if I pulled outward on both sides, the piece can be removed. Replacing it is just as easy, position it and snap it back on.
When I removed the plastic cover, I notice that the spring that holds the wiper against the window is hooked to a hole in the arm.
Even with the plastic piece on, it looks like you can stretch the spring so that the hook clears the hole using either a small screw driver or a long nose plier. Maybe if you use a plastic card, such as a credit card, you can unhook the spring.
I didn't actually try removing the spring since I didn't want to scrape off the black paint on the spring. Once the spring is no longer in tension, you should be able to pull the arm away from the rear window to change the wiper blade.
