Hello. I am new Cadillac owner and have a question about my 02 Cadillac deville. I purchased for next to nothing and was told it had an electrical problem. I bought a new battery(79) series and battery cables as well. I connected everything and have power to the rear and front fuse boxes, however I have no interior lights, dash lights, power locks, window operation... nothing. I am stumped and need some assistance. I did notice however the lights on the doors do work but nothing else. Any help is appreciated. Thank you in advance.
