2017 Expedition BCM Obsolete? Now what?

[TheOldRazor]

Hi out there - new user here - I have a 2017 Expedition which experienced driver's side rear brake and directional light failure. "no problem" I thought, " I'll just change the bulb." Which I did.
No good - still no brake or directional light.
I replaced the socket.
No good.
Off to the Dealer I go, whereupon I am told the PCM [ or to some the BCM ] controls that light, for braking and directional. Odd.
So I ask them to order one.
No good. They tell me they don't make them anymore. They recommend I send it out to a specialist to have the board checked out.
Which I did.
It came back 'unrepairable' circuit board failure.
So there I am, Ford technicians telling me I am out of luck. There is no way I will pass my state's inspection. Boat anchor. They suggest trying junkyards - for my only 8 year old truck!!! So I did - no luck.
But then, luckily, one of my friends wonders aloud if he can wire the light to my trailer hitch, which DOES seem to get a brake and directional light.
"Be my guest", I reply, " because if I don't do something, I will be learning the bus and train schedules to everywhere!"
So he did it.
Good.
It worked. Huzzah!

This long winded story is my introductory message asking fellow Forum members - does anyone else have this problem or is there some way I can get my hands on a PCM/BCM for my 2017 Expedition? I am told to write the NTSB which I'll do but I thought I'd try here first. Thank you!

So, I had a problem in my 2016 EL where the tail lights would blow the bulbs; on both sides. Replaced them twice, and got the same thing within minutes of replacing.

Took it to the dealer. They said they fixed it. Great!!! Ran good for about a week. Then, no tail lights. Checked the fuse to find that those idiots just replaced the fuse with a higher amperage one. WTF?!?!

All I could do was be mad at the fact they could’ve caught my vehicle on fire. I didn’t pay for that “fix”… only the original reason why it was there. Can’t remember for the life of me what that was.

Now I’m wondering if it was a PCM issues as well. Hmmm… Well, it’s someone else’s issue now.

Hope you get that figured out. Should you need any detailed wiring diagrams to troubleshoot that issue let me know. I’ve got access to just about all things on the road passenger vehicle wise.

@BlackBetty - thank you SO MUCH for the offer! For now, the wiring workaround to the trailer hitch is working like a charm, and I am still searching, hoping and actually praying that they either make the part, or I can find one somewhere lying in obscurity.
Thanks again!

Get the part number off of your original BCM. Find a used one on Ebay or from a scrap yard with the same part number. I'm a mobile mechanic and program used Ford modules all the time. Most decent shops should have a scan tool capable enough to run the PMI (programmable module installation) procedure on your replacement BCM. You will probably need 2 keys to perform the anti-theft (PATS) parameter reset function once the replacement BCM is installed and programmed, the vehicle will not start if this step is skipped.
