my Mazda CX-5 SUV or more likely CUV has a "moon roof". When I open it, there is a thing that pops up and has several "teeth" about 3-4 inches wide with 3-4 inches gap between them. I noticed that with that up there is some noise, if I reach and pull it down the noise is reduced a lot. I wonder what is the purpose of that thing? to me it just makes noise.
