Hello, yes I could completely renew the window lifter but I want to prevent it as well as possible. What bothers me about the whole is that if you let the disc down completely and want to drive up again it goes up max. 1-2 cm and then nothing more, even silicone spray or Teflonspray does nothing, only with the fingers try as well as possible to pull the disc up so up max 1/3 high, then it runs alone and like if nothing would be completely high. So if you it takes exactly the problem lies only in the lower area, have had also already open and me the sliding rails or. sliding bodies looked which so far look good and yes lubrication is also available. The sliding bodies and the disc are yes as far as I can see correctly mounted, means they sit according to the notches as they should and yes looks as that you can not adjust the disc here also not over the cable pulls which run accordingly on the turning roller, this e are provided with fixed cable holders , even these cable hoists run smoothly at least when I move them by hand . What could I still do here so that the disc can be closed again normal ? Does here possibly someone have a tip for me or there is any other possibility , would like to make as said everything completely new , if possibly it is only about a small thing . Am rather for repairing rather than only parts exchange and produce garbage , ok sometimes it is no different . I always have an open ear about good tips and advice and thank you for your active information. Greetings
