Renault Espace IV - Problem z płynnym otwieraniem szyb, przyczyna, naprawa w 10 sekund

Hello. Today, on a slightly different note, I'm talking about a window problem in my Renault Espace IV. I accidentally wanted to open the window, but due to the season, I didn't have to do it very often. The window started opening in increments of about 3-5 cm with a single click of the button. This problem affected all the windows. What could have happened? Check out the video.
