F350 electrical nightmare

[PLhunter]

Throwing this out there. I’ve had an electrical issue with my 2020 F350 for the past two years. It’ll throw codes and refuse to start occasionally when cold and wet. Not every time it’s cold and wet. But only happens when it’s cold and wet. Then most of the time after a couple days it’ll fire back up again. Occasionally with a code.

It’s been in a half dozen times for this issue and Ford can’t figure it out. Battery junction box has been replaced and all relevant tsb’s have been tried.

Anyone just happen to have had this issue or know someone who has? I’ve looked on forums and the fixes they’ve tried have worked for others but not me. It’s left me quite stranded a few times.

Previous generation has a connector behind the parking brake pedal that has been known to cause such issues. The next time this happens hard release the parking brake pedal or find the connector and wiggle it. If the truck starts up, then you've found your problem.

This is Rokslide. These are the only acceptable answers to questions posted in threads on this forum.

Sorry, what was the question again?

Just kidding, OP. I do not have any insight to the issue you are facing.

Giving this thread a bump with a little humor in hopes that someone can help you out. Quite a bit of wisdom and experience to draw from the members here.

Good luck!

Roads are going to start getting icy here pretty quick........
