Sunroof doesn't move while closing

[boss]

Hey Everyone.

Recently there is a small issue in my C230, 2004 model. The sunroof is creating a bit trouble these days. When i open the sunroof, its really smooth. But while closing it, it makes a clicking noise, and doesn't move. I have to push it manually and then it close. I know its not a big problem, but somewhere its irritating. Can anyone tell me what kind of issue is that actually and if there is a was to solve it by own.

Seems like a mechanical issue with the mechniasm fo sunroof. But the worst part is, if there is any probem with the sunroof, there is not repair possible because of the sensitive mechanism. It can only be replaced.

So does that mean that i have to get the complete sunroof replaced?
