Electrical problems

I bought a project car and it is becoming a headache! It is a base model 2002 chevy cavalier. It has no headlighs, no wipers, no drl, the service light is on( no codes stored) and the trunk will randomly open. I have been all over this car with a test light done a lot of reading and it all points to the BCM. I am hoping for conformation from some one on this. THANKS!
