Side mirrors, power windows, heated seats, window washer pump, power locks all went out at same time. Wondering if some master fuse or what?

Good evening.
The one thing they all have in common is the body control module. This module controls all the items that you have listed as an issue.
You may need to either have it re-flashed or replaced to get everything back on line.
