it might be your BCM, if it is I'm sorry, cause that's what happened to me, 750 dollar repair that includes part and labor ebay has them way cheaper but you need them unlocked to your vin or something, then you gotta unscrew the plastic piece under the glovebox there are 2 bolts, 1 showing and one in a hole, it looks really easy to get out, I didnt do it myself but I did bolt my neons up under both passenger sides and I had to pull them down
good luck man, Mine started with a radio install and not unplugging the negative from the battery, I did at first then had to move the car and didnt unhook it :|
