Trouble starting windows going down on its own, no sound on stereo, horn blows on its own, check engine light on and service brake system light on.

While that could be a body control module failure, the first thing to do would be to get a dealer level scan tool and read any codes stored in the system as well as the freeze frame data and see if there are any clues to the problem in that information. Then determine a course of action.
