Mercedes-Benz ML350 Problem
Average Mileage: 90,857 mi (80,000 mi - 101,715 mi)
2004 Mercedes-Benz ML350 sunroof made a cracking sound when we opened it, now the inside shutter hangs up when opening or closing and the sunroof will open to the vent position but it will not slide back, it will try to slide back but it seems like its is hanging up on something that I cannot see, Please advise Thanks.
