I have a 2008 Subaru Forester. The interior lights don't work. The overhead dome lights and the two maps lights don't work either. I have checked the bulbs they are all fine. I have changed fuse 13 which is supposed to control interior lights and the radio. It seemed fine but I changed it anyways. The lights still don't work. Everything else seems fine. I have never added electronics to the car (cd player, radio etc). What else can I check?
