Got in my 2020 Raptor (802a pkg) today and the following functions in my upper console (in front of upfitter switches) are not receiving power: All Map Lights, all interior lights, HomeLink, Passenger and Driver Vanity Mirrors, Retractable Sun Shade and Pano Sun Roof-All not receiving power. However, all upfitter switches and rear window slider do have power and are operating nominally. Searched forums for a solution without much success. I checked Fuse 27 (Sun Roof) on the Passenger Compartment Fuse Panel--Fuse is Intact. I checked Body Control Module Fuse #4 in the Battery Junction Box--Fuse is Intact. I unhooked the battery for 20 minutes and then reinstalled post cables to do a hard reset--No effect. I removed the upper console and checked all connections--All Intact. Still have no power. I'm wondering if one of the pin connections may have gone bad or if a ground wire came loose. I did find a recent F-150 diagram illustrating a wire harness that connects all the affected accessories in this upper console (attached). All the affected accessories I am having problems with are connected to this wire harness.
Root Cause Possibility: The only thing I did recently that I can think of that may be related to the root cause of this problem was turn off the auto wiper rain sensor on dashboard control panel from auto sensing to normal. I did that a couple days ago. Coincidence or not, this is the same window of time I noticed my cab lights not powering on when I exited the vehicle. I see from this diagram that the rain sensor module is connected to the same wire harness as all the other affected accessories that no longer receive power. It seems to me that there may be a correlation between me turning off the auto wiper rain sensor and these other issues. They all share the same wire harness. I'm wondering if when I switched that module off, it failed and as a result, that switch is preventing all the other switches from getting power.
I do not have a check engine light but when I hooked up my code reader to the OBD2 port, the truck is throwing two undefined codes that I can't find much on: U023A and U0256. These seem to be "Lost Communication Codes" with the main computer network and lost communication with "Front Controls Interface Modules." I am reaching the limits of my amateur electrical troubleshooting and not sure what these codes mean or if they are related to this current power loss on the upper console.
I'm just barely out of warranty 37,000 miles...of course. Any suggestions before I have to take it do the dealer? Help??
