OOdles of electrical issues

It started out that the rear passenger door would not lock or unlock with the remote or the buttons on the door. Then it proceeded to the rear drivers door and the front passenger door. Now none of the doors except the drivers door have locks that work (unless manually Locked) or windows that work. What is wrong with my car? Any ideas?

What is the year & trim level? If it's a 2000+ bonnie, there are 10a fuses in the rear fuse block (under back seat) that run the control modules in each of the doors. I'd start there checking fuses. Also, communication are via serial buses between driver door module & the other 3 doors modules.
