Are you sure it's fuse 95? That controls the right front headlamp assembly.
I sent him some info in a PM and at first I thought the same thing. Honesty I think there are actually 4 generations of raptors. 2017-2018 and 2019-2020 have enough differences that 2019-2020 should at least be gen 2.5

Nope, and I tore everything apart this last weekend to double-check there were no loose wires or anything shorting from the front end to the firewall and under the truck back to the tank. All signs point towards an internal short coming from the evap purge valve or other related codes. So instead of spending more time ripping through everything, I've got it scheduled at a Ford dealer for them to figure it out. It's only got 31k in miles so it's covered...

I have had vehicles were I do that and the problem goes away for days, weeks, months or forever. Just by moving things around, what ever was "touching " ground, isn't anymore. Just saying.

and it stayed off for about a week then yesterday evening, fuse popped, & the check engine light is back on. Going to the dealership Tuesday, with a sign that reads “Happy Hunting” I’ll update once they locate the issue.

Did mobile detailer use a pressure washer? If so, the possibilities are many...

Update - bank 2 oxygen sensor wire somehow got enough slack to randomly rub on the drive shaft, wearing down the insulated wire and when all conditions were just right (speed, bumps, wind, black magic sorcery) the exposed wire would touch the spinning driveshaft and cause the short which would blow the fuse sending all sorts of codes for evap, purge, o2 sensors, start/stop disable, etc…Fun stuff…So if anyone ever has fuse 95 - Vehicle Power 2 continuously blowing, you’ve at least got a spot to start your search.

Extra thanks to all that provided feedback, appreciate all the assistance

Glad they were able to find it.
