Hate to put it this way but…It sounds like you have no clue what is wrong, what the repairs should be, and to top it off you are probably just making things worse by throwing random parts at the problem. Go see a real mechanic.
My top of the head guess is a bad body control module but I have to agree. Take it to a professional you trust.
