I have a 2015 19' FC. When washing the exterior I usually take a plastic garbage bag and use it to cover the upper and lower access doors to the refrigerator. These are the vented doors. No reason to get much water into these areas...
Any plastic tool that is somewhat stiff and thin can be used to gently work between the glass of the window and the rubber seal (while standing outside). You are using it to break the seal that can occur between the two given summer heat and a dried out rubber seal. I use a tool I got for taking apart electronic gadgets from www.ifixit.com
but you can get one that is used on car interiors as well. Keeping the rubber seal lubricated with Aerospace Protectant 303 (or whatever you use on your car door seals). Don't get in a hurry and be gentle - you can rip the rubber or crack the window.
These window poppers can be installed and will allow you to open a stuck window without having to go outside - http://www.seeyoudowntheroad.com/sho...indow-poppers/
In the bag with the radio's instructions should be two thin metal pieces about 1/2" x 6" and about 3/16' thick. You slip them between the radio and the tray to press in two tabs to allow the radio to be pulled out of the tray (explained in the radio manual or go online to get a copy).
When I search this excellent forum I usually get better results by using google directly with a search such as "airforums stuck windows" or "stuck windows site:www.airforums.com" (don't use parens).
