check auto light fault

[seagrave]

hi I wondering if anyone can help . I've got a megane mk3 and the check auto light has come on and all my interior lights have stopped working . I dont think its a bulb as all of them have stopped right ? I've not changed any bulbs that leads me to believe ots a fuse however after checking the manual and their websites their diagrams are useful as a chocolate fireguard and none of the listings even mention interior lights can anybody help me thanks
