Where do the vents just below/in front of the windshield go? I am wondering if they are not intakes for HVAC, and my car constantly has a musty, moldy smell. It's the first year model with ~70k miles, so not new. The problem I have it I for years it has often been under a couple of crepe myrtles over my driveway. This tree drops all kind of stuff on my car, including aphid waste (it can feel like a light sprinkle at its worst). I have to pull out bits of branches, leaves, and flowers from the around the wiper base and the vent that goes under the hood. So I bet those vents have also accumulated a lot of crap inside. So anyone know of a way to get in there to see, and maybe clean it out? Or is there another way inside? I am about to have the car professionally detailed to see if that helps, but it's never really been that dirty. Yet the musty smell persists, and I really hate it.
