Something is blowing out the fuses for the ETC, hazard, the TCM and the power window fuse. I order a short and open end finder and it looks like there is also no power in the harness going to the alternator. Also I didn't mention I found an active short which was pulling the battery down over night which was a interior light fuse and remove it. Over the five years that I've had this car I've had to replace the alternator 4 times. I don't know if they were bad or it was part of something going on that got worse. Hope you have a solution.

Hello,

You have a auto light control module that actually power the windows as well. This module is behind the left side of the dash. It's probably bad. The fuse you pull stopping the battery drain is also connected to it. I attached the diagram showing that part of the circuit. You should try to get a scan on it as well to see if you have any codes that were stored but seeing this module is connected to these same separate circuits it most likely is your issue.
