On my 2011 Saab 9-5 turbo6 the sunroof was opening and closing perfectly fine with ease. As well the sun cover was closing and opening with ease, suddenly they won't open or close, neither of them will. But when I click both of the buttons separately to see if the roof will open it'll make a noise as it's making connection but won't open it. Same with the sun cover, it's halfway open but when I close or open , just makes a tick noise but won't do anything . So complete power is running through the system. Common problem ? Please help !
