Vincent Prince

Ok guys I've got a problem, Every time I close my door my interior lights come on(same as when I lock it) and then when I open up the car they go off.. it's like one of the wires have been switched somewhere but the only thing that's been done to it is that it had the roof lining done...and then it started but I've taken it back down to have a look and it looks all fine. Also the two light above the mirror don't work anymore. Dose anyone know what's happen or how to fix it ? VinCe.
