Your problem does not resemble mine. Mine was caused by a leak in the weld on the drivers side in the windshield gutter underneath the rubber seal. Water had leaked in and caused problems in one of the electrical components. You should be able to find my posts that addressed the problem. However, I don't know if your problem is caused by the same thing.
I have also been communicating with Ford online. Today they told me they talked to the dealer and agree with what he says because he has been "trained". I can't imagine the technology has gone backwards and it is a safety hazard. Anyone have a 2012 expedition that can tell me if this is the same on your vehicle?
2001 Ford Expedition
I left the lights on and the battery was dead. I jumped the vehicle and it started right up. When I disconnected the jumper cable, the vehicle died. I reconnected the cable and it will not turn over. No ignition, no lights, no horn. I let it charge for a few minutes before I disconnected the cable again.
Battery output is at about 9V.
I have the Owner's Guide with the fuse charts.
All of the fuses under the dash are still good. I can hear a faint, steady, slow (one per second maybe) ticking at the box like a relay but I cannot determine the particular one.
All of the fuses in the Power Distribution Box under the hood are good (Mini and Maxi.)
I removed the Maxi fuse for the "Junction Box Battery Feed" and get 9V across the terminals.
I removed the Maxi fuse for the "Ignition Switch Battery Feed (Run/Start Circuit)" and get NO voltage across the terminals.
I am going to try to find a schematic and continue troubleshooting, but I was hoping someone could shorten my search. I am a computer guy, not a car guy, so electricity doesn't bother me. I just don't know the flow to trace in sequence.
Thanks in advance for your assistance.

I can help !!!! on the ps r/ door.. Lift up the plastic footstep in the door jam right next to the rug just pull hard and lift and look for water and a wire harness if wet... keep plastic off and heat or air dry ..
For combined problem : Advantrac not working + 4x4 flashing + heated seats no power + headlight daylight sensor disabled + radio stays on when door opened + more
- CAUSE -
There is a purple wire splice, under the driver door sill-plate, that is likely corroded at the splice. This wire is the UBP feed to the communication bus from the affected modules. It mimics some of the symptoms that occur due to moisture on the GEM module, so if the above description suits your problem, then it likely is the corroded splice.
- FIND and REPAIR -
Remove the plastic sillplate / footplate. Cut away the black wire bundle wrapping. Find the purple wire that is spliced to two purple wires. Pull the wires with force at either end of the splice, if they come apart, cut back the wires and splice. If they don't come apart, then carefully cut away the heatshrink to inspect the splice, if it's okay, then remove the metal plate along the door sill and continue to inspect the wire rearward, and then follow the wire forward and up the column.
If you google for "ford expedition purple splice advantrac seats" you should be able to find similar posts. Good luck.

Clicking sound intermittently (relay area???) Or by steering wheel area..
Causes windshield wipers front and back intermittently work or shut off, as do power windows, windshield wipers and windows both do not work at the same time when this happens.
Now dome light clicking on and off. Dome light stays off when door closed.
Bad relay? Window leak? Puzzled where to start. Some people say electrical, some say could be a relay? Bad fuse? Leak?
