[Superlocked]

All doors are perma locked and cannot be opened by any means (can open drivers door with key only). Replacing only the driver door actuator fixes the issue but a short in the fuse box will cause this to get blown out again. Looks like I need to replace the fuse box, how hard is it to replace this? Looks like its just screws and unplugging the wire / replug rescrew and let the car run for 5 minutes to learn the new box.

Slow your roll man. If a new fuse is blowing every time, then there is no resistance for that fuse. That means that energy is flowing full speed back to the ground, chassis, battery, whatever you want to call it, with out going to the locks. First, you'll want to make absolutely positive sure that it's in the box before you replace it. Take a multi meter and hold one end in the output side of the fuse and then the other to where power enters to what you're checking. Hold them there and activate what you are testing. You might get some thing. Then so the same, but do it from the fuse to ground.

Maybe this will help if it is the fuse box and not something shorted externally.
This repair is still working well.
