I have a Maytag Model RSW24E0D. What is the best way to remove the rear panel to unclog the freezer drain line?

Unplug it and remove the screws and it should be easy, but to unclog the freezer drain you need to remove the cover to the evaporator and blow out the drain at the base of the coils in freezer. Here are some manuals: https://dl.dropbox.com/u/8010163/Maytag%20Refrigerators.zip
