My 2012 C250 wiper fluid doesn't seem to spray out when I push the wiper stalk all the way in. I checked the fluid resevoir and it is full. I did some searches and I see some people have those problems on other and older models, but a brand new car? Anyone know of anything that this could be other than a problem that I have to take it back to service for? I mean, I will no problem, but I would hate to take it down and find out i'm just an idiot doing something wrong, lol.
