This needs a good professional diagnosis.

The body control module is known to fail and cause these issues. I've seen several of them with concerns like yours. Since these functions are all computer controlled, I wouldn't attempt a diagnosis without having the benefit of a dealer-level scan tool so I could test computer inputs and outputs before condemning anything.

A professional diagnosis will save you money, by identifying the failed part correctly the first time, and keeping you from buying parts you don't need. This isn't a very DIY friendly diagnosis or repair.
