My CX5 overhead lights would not turn off two days when I closed the door so I turned the switch to off. Next morning the key fob would not work (brand new battery); I got no reaction from lights; I cannot start it without putting the fob next to the start button, no infortainment or back up camera; the door locks are not working from the interior, and I have no interior lights and the check engine light is on. A neighbor checked for a "code" and nothing came up. We checked the fuses and the 54 "room" fuse was blown. We replaced it without a new mazda fuse and that one immediately blew. No other fuses were bad. The car starts right up and runs fine - help!
