Editing to update.
My interior lights are all off and pushing the buttons on the headliner, adjusting the switches that Tim the dash, etc have no effect. Can anybody help me identify the related fuse or other probable causes?

I visually inspected (removed, looked at, reinstalled) every fuse in the kick panel and Found nothing. I checked the manual and it does not label the fuse related to interior lights. Wish I had continuity checked every fuse, but I’m hoping the forum can give some back on this and help me find my way...

The upfitter switches are illuminated. The dome light switches are not - and NONE OF THEM do anything.

Local dealers are not great. I bought my truck from three hours away. I really don’t want THIS to be the reason my truck spends two weeks at the dealer.

Thanks for assistance.

Hey all,
The dome lights are out (including illumination of switches) in my 2019 no-sunroof lariat ultimate with LEDs and up fitters. I checked all of the buttons I could think of. Theories? Is this a kick panel fuse or somewhere else?

I haven’t had much time to catch my breath let alone mess with it this week... hoping some quick forum advice will reduce my irritation level!

thanks!

 

Sounds like a blown fuse.

Grap your owners manual and see which fuse controls what is out and go from there and the manual will also show and tell you where the fuse panel is located.

If you haven’t exceeded the factory mileage warranty and if you don’t want to deal with the frustration, you should just take it back to your dealer and let them deal with it.

 

I got around to trying to address this.

The manual has no reference to the fuse that drives the interior lights.

So... from there I removed and inspected every fuse on the passenger kick panel. None were bad by visible inspection, but I suppose I could have missed it.

Anyone with the service manual or electrical diagrams have some help to offer on the fusing for all interior lights?

Thank you.

 

Not sure if this is what is causing the problem with your truck. I know when I picked mine up, none of the interior lights were illuminating and I found out that there is a button located near your Upfitter switches what will turn all the interior lights off, even if you open the doors and such, they will remain off. I do not have access to my truck at the moment, so I cannot tell you the exact switch. From what I recall, the switch has a picture icon on it, showing a rectangle that looks like a 2 prong plug with a light icon under this with a line through it. I believe it is the middle button of the five. I can check later if someone else has not already responded by then with a better description or such.

 

It’s not the door mode only. None of the buttons on the header for lights (that turn lights on no matter the state of the doors) do anything.

anyone have a theory on the exact fuse Incase I missed it? Is this not a lock panel fuse?

I’d really feel defeated to take it to the dealer for interior lights out.

 

Not sure if this will help but when I picked up my 2019 F350, nothing above the pillars worked. Sunroof, dome lights, clearance lights. Long story short, it turns out there was a pinched main wire that had a screw straight through it from the factory. Took the dealer 2 days to locate the issue. Never even got to take the truck home on day 1.

Hope this helps!

 

Thanks for the response. My cab lights and up fitter switch illumination all work. This really seems isolated to the interior lights

Yet... the blasted manual does not sight a fuse. If I could figure a fuse I could do a continuity check at least.

The system being totally off makes me think this isn’t a BCM issue.

 

If you have cab lights is it possible you've had a water leak that has shorted the switches?
Just throwing stuff at the wall to see what sticks.

 

Well... pulled the unit down. It’s fried.

this will be fun sorting out with the dealer...

 

Took a gamble that f150 part would interchange. Success.

 

Oh my that's is very disheartening to read, I'd be so upset
