Hi Guys, this is an old thread but I thought I would add my 2 cents. I have 2009 B200. I live in Canada so below 0 temps are normal. The hatch button wouldn't click anytime the temp was below -2. I was getting frustrated so I took it apart and brought the whole chrome assembly inside, after a couple of hours it thawed and the button clicked fine, so I took the hair dryer to it and then the water started to come out I bet 15ml 1/2 ounce of water came out. I am going to let it dry the rest of the night and I looking into ways of resealing the component before I reassemble it. Anyways I was quite relieved to find that the part was fine just a design flaw. I seem to have caught mine before there was any damage.
So coles notes take it apart and let it thaw and dry, and you should be good to go.
