Good evening to everyone, my beautiful C70 is just keeping me busy. After I was allowed to invest 170€ in various repairs & TÜV now annoys me the window lifter driver’s door (is a right-hand handlebar). When I press the corresponding switch the disc goes down normally, whereby it crashes pretty much in the last part. When closing starts the problems. The engine tries to push the disc up but does not manage. I sprayed the seal with silicone spry – but it did If you push the window lifter switch down and then up you can pull the disc with your hand a piece up. To close the window completely I have to repeat the latter several times. In which direction should I look from your experience? Switch broken? Or the mechanism of the FH itself? There are repair sets – I was advised not to buy the whole unit? Newly there is no more… Did someone of the FH not really help. Such a mechanism for the right front door that can be delivered to you? Thank you in advance for your answers. Ramón
