Have u taken off the door paneels yet?

Could u check the wires of the power windows?

About the locks.
Take off the Paneel (s) and try to get a clear look at ur Motors and studs, that controls ur lock.

Perhaps, theres somethings broken.
Or ONE of ur lock motors is bad. And the systems prevents all doors to lock.
Lets say to show u that one lock doesn't work.

And About the windows. In modern cars the most systems are connected all together by the CAN Bus.
I'll try to translate a text from my school book
