Fuse Name/location for Front Dome Light?

ISSUE: Dome light will go on when I use button or open door. Rear ceiling light does power.

No blown fuses that I can see.

Looking at the fuse diagram, I don’t know what to look for:

Can anyone help?

I am not sure if my 2011 fuse info can help. The factory fuse table has "ceiling lamps" which is on fuse 17. Since it's "lamps" it could be for both front and rear lamps. Is your rear ceiling light working?
The fuse 17 is shared by a few other items such as auto-dimming rear-view mirror, garage door opener, makeup mirror lamp, panoramic glass roof, rain/light sensor, reading lamps, tilting/sliding sunroof.

Those should be listed under “Courtesy Lighting” and the Fuse Allocation Booklet shows 4 fuse locations listed for them:

2
3
39
41

Check those out and let us know if it’s one of them.

I thought courtesy lights are those on the door bottom. If not then what is ceiling lamps in the booklet?

UPDATE: Still Unsolved.

Removed the 17 fuse. No ceiling lights worked after removing it.

No issue with rain sensor.

I have to assume that this has shorted inside or the button on the console is bad...

Did you ever manage to sort this out? I have the exact same issue. Dome light works when opening the door and using the key but none of the buttons work for the front dome light. Sunroof button works as do the rear dome lights.

I replaced the unit by buying a used one off ebay. Issue was resolved.
