Maniac said:Are you certain the bracket that secures the plug into the roof module is fully pushed into place? It could just need some gentle encouragement. The type of clip/bracket ensures that when pushed fully down the plug is pulled into the socket making a better connection. It should be possible to just pop the top of the clip away from the notch in the plug to allow you to swing it back up and the plug will come out. Get some extra light in there to see what you're doing and you'll see the notch that the clip must be prised (gently) over before it can swing up. Its fairly straight forward provided you take your time and be gentle.. oh and don't have keys in your pocket to make the car try and crush you.
It looks as though it has been removed one too many times in its life and the mechanism on it has worn away so now it is stuck in there. Really don't know what to do - it's in there working but I can't return any of the trim
