My sunroof makes noise from left side, as a piece of iron that vibrates when car go in the hole (and during accelerations too), I opened id ant then I checkedthe situation: it miss one of two its supports (the left one). Now it's working without it, so sometimes it blocks itself stopping movements (many times no problem, it depends if that piece of iron can move free or not). Anyone can help me how find that support missed and how mount the new one? Thank you very much.
