indicating  a fault with the system at the
same time the door lights when open do not
work, the key fob to open the doors does

Had the EXACT same symptoms. My problem was a bad Driver Door Module (DDM). It had power going in, (so not a broken wire) but no power coming out, Replaced and fixed all problems.

There are three plain green wires come together into one green wire is broke off inside the black rubber cover by the driver door hinges. It's happen on my 2009 Grand Marquis, so I had to add the wire to replace two broken wires to make the power door, mirrors, rear defroster, and dome lights working again.

Explain some more about this green wire inside

it is a ground wire separate and fix it in the door loom
