My new to me 2022 F250 Lariat would throw a "Memory not allowed while moving" and "Blind Spot System" and Cross Traffic System faults, and when it did, it would kill the auto HVAC. The HVAC would come back to life when the right turn signal was actuated. This would start after around 200 miles of driving. Really weird. The dealer found a bunch of faults related to battery voltage and reset the BMS, but did no other repairs, and it did not resolve the issue.
I suspected an issue with the passenger side BLIS module, so this morning I traced down the wire harness and found two connectors mounted to the frame aft of the spare tire. I opened them up and found this:
I cleaned with contact cleaner and dielectric grease on both connectors. There are two on the left side of the frame as well, but they were clean inside, so I just just greased them up. These connectors are in a vulnerable location so I need to try to better waterproof them. It acted OK on a short test drive. I need to take a road trip and see how it does. This would appear to be the smoking gun at this point.
Idaho, winter driving? Salted roads? That connector has a lot of mud and gunk on the outside. If the roads were salted over winter, it's likely the salt/brine solution made its way into that connector. The green corrosion is the giveaway, IMO...
My guess is that you found the issue. Good luck, hope it was just a simple clean and seal matter. If it were me I'd probably see about getting a spare connector, just in case...
Its too bad this is still an issue on 2022's, the '17s had it at first. Thought Ford would have fixed by now. Salty roads, mud, brine...you name it, it SHOULD have been fixed years ago.

The truck is new to me - I bought it in early April. It came from Western Canada and apparently spent most of it's life on dirt roads - either the oil patch or a wheat farm - based on the amount of dirt I have cleaned out from the frame and everywhere else under there. I don't know how to identify the connectors and harnesses. I would like to order replacements if they weren't horribly expensive and readily available. I need to get back under there and check any other connector I can find.

I did find several outfits selling take off harnesses from trucks that get converted to flat beds before delivery, so connectors look new, compared to mine. This is the tail light harness. I am debating if I should just pull the pin and order one and replace this proactively.
Will do. I ordered a take out harness. When it gets here, I will install it and check all other connectors back there.
More than likely that harness will be in like-new condition, as flat-bed conversions are typically done on new vehicles. So, you should be getting a practically new harness for a substantial saving (as compared to just walking into a dealership and buying it from the parts dept).
Keep us updated as to the condition and price, and if they're available to be shipped from your source. I'm sure there'd be a lot of folks interested in getting a complete harness for a discount
