hi,
i have never had a problem with any of the sunroofs in any of the benz i own but what you could try is to first degrease the tracks good. get all that 23 year old grease out of there. Then have someone hold the switch and help the sunroof to close. open again and repeat. Try doing a search under sunroof grease or sunroof lubricant and maybe that will give you a substitute. hth mike
