Renault capture window lifter problem

Hi I’m new here …. It’s about a Renault Captur bj.2013 Have there ever been a question of window lifter function driver’s side…. During the ride, the disc suddenly goes down… Is fun when it’s raining… Can’t be driven up again for a short time… takes a few seconds… and you can either pull the switch up or push down and the disc drives up… My wife drives the car…. Did I have a switch removed… I drove to Renault to buy new switch 37 Euro ca … In time my wife comes from work… Window lifter has gone down again… And that without switch..????????? And that’s what again a rod money cost … what I didn’t see the car from 2013 so slowly one should know the sources of error from this vehicle?????? Renault says of course? first we have to look for the error and replace different parts? What of course a rod money cost … what I didn’t have to see the car from 2013? but what on the driver’s side?? What is it all?
