I have a renault megane 2.0 2005 cabrio. Its roof was functioning well. Then suddenly it stopped working. When I press roof button there is no sound no “beep” - anything at all. “Canrio defect” indicator shows up. On the other hand read windows are also not going down neither when press the roof button nor when I press the separate window buttons of rear windows. Please could you advice me about what can be the problem? Thanks
