Tried my drivers door window today and nothing's happening. No sound from the switch or motor but the interior light dims when I press the button. I fitted a cube regulator a while back but the symptoms are different this time. Can anyone recommend the correct switch and motor in case I need to buy new ones? I'll take the door panel off tomorrow and have a quick look. Was there ever a 3 door Megane with wind up windows?? I'd have that fitted if I could.
