The wall is held on with a bunch of screws. If you are going to remove the wall, you will have to take the cover off the switches and if there is an outlet, that also. You will have to take the switches and outlet loose so you don't pull them loose. Before I went that far, I would try to get the blockage out by using something that was a little flexible and try to push the blockage out, or get something to grab it with and try to pull it out.
