2004 Honda Accord, 2.4 L, Manual transmission, Sedan. Just bought the car, both rear windows and door locks do not work at all from any position, one thing that I'm not quite sure what it means, is that the horn will honk to indicate all doors are locked regardless of the position of the rear door locks. Any guesses as to what would cause this? It's almost as if the car thinks it is a coupe... I would greatly appreciate any advice as to how to diagnose/repair this.
