DUDE! my 2 yearold has done that. It was missing for 2 months. Then one day guess what i see him playing with in the middle of the living room.... Everyone looked for it for about a week and then i would look for it every so often.
Yeah same for me about everything working. I did however find the water isnt coming in when the door is open nor the door jamb. Its from up under the side of the dash. Its weird. I have to investigate further when i take it to my brothers shop.
