Ok, I've read a lot of topics on this forum and I've checked fuses in under the hood and under the back seat and haven't found anything.

My sun visor lights do not turn on at all. My interior lights (front and back seats) do not turn on when the buttons are pressed, but they do turn on when the doors are opened or the driver's knob is turned.

And to top it off, the 12v "cigarette lighter" in the ceiling does not work. (The others do.)

-What fuse is for the sun visors? I don't see that labeled.
-Is there something that would affect all of these issues?


May have something to do with it:
A few days ago, a lot of stuff wasn't working. On top of what I listed above, the power door locks didn't work (from the keyring, from the inside buttons, or when shifting into park/drive). The trunk wouldn't pop from the keyring or the button in the glove box. But all that started working again.... weird?


Thanks for reading!

By the way, I checked the Interior lights fuse, and the cigarette lighter fuses. I also swapped the interior lights relay with the trunk relay and I still have the same problem :(

The fuse that feeds the visor lamps is "INT LP" 10amp fuse in the rear fuse box. It feeds all the interior lamps. The circuit splits at least 5 ways in splice pack 306 (SP306). One of those circuits goes to the vanity lamps. I would take a look at that splice pack and see if there is any corrosion in there. SP306 is located about 3 inches to the left (drivers side) of the rear fuse box. It will probably be wrapped to the main harness with electrical tape. It is a black plastic box about the size of a small match box. Looks like there should be 6 wires total going into it.

I checked it. No corrosion and all the wires looked like they were in there tight.


What about the ceiling cigarette lighter? Any idea what fuse that one is off of? I've already checked all fuses labeled "cigarette lighter".

Thanks!

Not sure which fuse, but that outlet was considered an auxiliary power outlet. Look for a fuse labeled "AUX PWR".

If the wiring is similar to the SSEi, there will be an AUX PWR fuse in the underhood fuse box. This is driven by the "Cigar" relay in the rear fuse box which is fused by the "Cigar" fuse also in the rear fuse box.

Thanks for the diagrams, Mike!

It looks like I want to take a look at splice S329 and Ground G404. It sounds like S329 should be under the back seat somewhere, and G404 should be in the trunk somewhere. Can anyone help me as exactly where I should be looking? Thanks!!

I had an almost identical issue. I found a loose junction plug much like the one under the rear seat. it was on the driver side trunk wall, about a foot behind the taillight on the driver side. Not very well protected from the impact of rolling strollers or sliding groceries... it is under the carpet so you have to remove some trim to get at it.
I hope this helps!

Holy crap that was it for me too!!

Thanks everyone!
