Gently pop down the head liner and you'll see some wires and clips that can use insulating.
If you have SAT and or NAV, turn your palm towards the roof and slide your hand in and up around the structural bracing just to the right of the antenna. You'll find some more wires that need to be insulated and secured.
These were the culprits in my car.
Good luck!!!
