the same has happened to mine , i called RAC who got the window up for me but then took it to renault and have said its going to cost over £300 to repair as the regulator has gone wich costs £150 but they have advised me to call renaults customer care as they have had many complaints and in some cases they have helped towards the cost , so im now awaiting a reply from them mine is a 55 plate so not long out of warenty
