Well its been quite a few months with my new truck. I have noticed that if I put the vent on it will start to fog up the side windows. Not the front like when you have a leaky heater core, but the side two door windows will fog a bit... Does the vent come thru the heater box on our trucks??? If so then maybe I do have some water in the box, but not real sure... I don't want to just pull the heater core for an inspection... but might have to. I don't see why the vent will cause fogging issues
