hi all i have a c class coupe 2017 model.
Whenever i activate the electric windows down on the passenger side there's is a horrible squeaky noise. i have attached a video for reference. I have tried some contact cleaner inside the window slot however has not made a difference.
Any suggestions? it sounds like its coming from the corner or something is rubbing. Only happens when the windows comes down not up
