Hello people, window lifter driver door cracks pathetic and stops in the middle, wants to change it, doesn’t know how, in which position I get the disc out, what does the disc do, if I have the guide rail of the window lifter out, how can I get it back in? So, I’m perplexed. Now you will say, window lifter has been described tens of times, have found no installation instructions. Kurt already disassemble his picture series about door, is also quite great, but no description of the window lifter. Who can help me? I am very grateful for any help, has certainly made someone!
