Sliding roof

Hallöle to everyone. I know, I know, my topic is described in detail and you can download the PDF. I also know the images that I have set up. My sunroof also sometimes has its own life. As you have probably already noticed, I am artisanal, how can I say, so a black slope when skiing is easier for me. Is there someone near Gelsenkirchen who can address the problem to me? Of course, no one has to do it “honorable”. Thank you.
