UL Rear Console Fuse

UL Rear Console Fuse
Hi there. I was cleaning my car today and noticed the rear console in my UL isn't working. The screen is blank and the seats aren't moving. The buttons to control the radio are working. I can use the button in the console to move the rear seats so they are working just not on the console. I can't figure out where the fuse is for this panel. Any ideas?

Please take a look at the diagram below, I suspect one of the connectors was disconnected accidentally. I would start with the rear power seat switch assembly.
...and after you confirm that all connectors are seated properly and the problem persists, then the next step is dig deeper into ECUs, fuses, and electrical components. Below are diagrams showing locations of these hardware...

Good luck, and please keep us posted.
Here are some more electrical schematics for the rear power seat system. The "control switch" of interest is shown on Page 403 (middle of page), and if you trace the power wire (G-W), you will see that it's powered by a fuse called "MPX-B1" on Page 406. This fuse is located in the passenger side kick panel junction box. You may want to test for 12V power on the G-W wire at the armrest connector.

Thank you. I haven't had a chance to take it apart yet. I was out playing with it tonight and here is what is happening
-LCD screen on rear armrest is not illuminating
-illuminated buttons on the armrest and the heated seat and sunshade buttons are not working
-power seat and power headrest and massager buttons are not working (the motors for the seats are working from the rear seat reset button on the front panel)
-buttons controlling all radio and AC functions are working, but are not illuminating
I thought maybe there was a lock button or something that shuts off those functions but that doesn't seem to be the case.

Ok took it all apart. I checked fuses and all connections. The main power cord into the armrest is causing this. If I jiggle it the armrest loses power. I was able to tape it in place and it is working fine. Not a long term fix however. Any ideas?

Did you actually disconnect the connectors (near where you "jiggle") to make sure there's no corrosion or lose pins? Can you post some photos?

Ok this issue has popped up again. I have taken the whole rear armrest apart and part of the seat checking the wires. Everything looks fine. I'm jiggling the main connector, and that is intermittently working. There is also a connector that is taped up and doesn't connect anywhere on the armrest. Is that normal???

I would unplug the suspect connector and look inside to see if there is any damage/corrosion in there. It may be as simple as cleaning the connector.

Hi everyone. I am still struggling with this problem. I have taken the console out, checked connectors, all looks good. Next step was to remove the seat back but I can't get the headrest up because they are powered. Should I just pull it up?

Reviving this thread - I'm experiencing avery similar issue with the rear seat control switch.
HVAC and Radio controls do not illuminate, nor does the LCD screen for radio controls. HVAC **** controls are intermittent and "stick" (either the green LED light stays on or off when you press the button to turn it on/off).
Power reclining seats, head rests, radio controls, sunshade, fridge, etc all work as expected.
Sometimes the radio screen will work, but will randomly turn off or will turn off if I press the HVAC control ****.
I've checked and cleaned all connections in the console as well as the rear fuse box. Also checked MPX-B1 fuse under the passenger kick panel. No dice.
