Yesterday, I drove to work with the sunroof tilted up. Went into the office and a couple hours later, i noticed that it got very windy. By the time i got out there, some sand/dirt got into the sunroof track and now when you open it, you can notice a faint grind of the sand/dirt on the track (sand is from snow removal trucks). What would be the best way to handle this? Would the dealer service center do it for me so I know it's done right?
