door lock questions

[Tbruz]

Door locks on a 1997 two door stopped working from inside the truck.
Not working from drivers side, passenger side or from rear barn doors; there is no sound at all when activating these door lock buttons.

If I lock or unlock from the key fob remote; everything works fine, all doors lock and unlock properly.

Because of this I assume the fuse is good and the actuators are just not getting power from the door switches
Any ideas; trouble shooting tips or schematics appreciated.
Thanks

switches also activate the relay that fob would so try fuse 13 it provides power to switches when key-less entry is installed.

Fuse 13

OK fuse 13(25A) is blown; what else fuctions off of that fuse?
Thanks

Fixed!

Thanks for the leads!
Lumbar wire on drivers side was messed up and grounding out to seat frame.
A few wraps of black tape around the wire and fuse 13 doesn't blow anymore.
