i have a obd2 vr6 golf 3 door, just last week the full closure has stopped working on the windows completely with the central locking remote fob, it had been working perfectly and the central locking does still work perfectly with the fob, but none of the windows close any more including the sunroof which is a pin in this weather, any ideas what could be wrong with it? fuse or something? please help, as far as i know it was a factory fitted standard one, fitted when bought new, thanks in advance
