Good evening MBWORLD. I'm having an issue with my sunroof. I have the dreaded grinding gear noise in my sunroof motor housing. But the sunroof opens and closes both ways, up and down and front to back. My issue is what is seen in the picture. Any advice would be greatly appreciated. Thanks in advance.
