Hello! I can't remember if I've ever posted here before, but hi! I have a 2008 Dodge Nitro SLT and I just wanted to ask if anyone knows anything about a water sloshing noise in the dash along with a grinding noise coming from the grill area? I've been hearing this sound for about a week now. Its possible that it may be air stuck in the system but i've tried bleeding as much air as possible out but the noise stayed.
