All interior lights out

2020 Tundra SR5

-door open, no lights at all
-can’t even turn individual overhead lights on

-battery is fine
-starts and runs fine
-dash displays all fine
-upper bed light is fine
-tried the panel switch in both positions
-a few exterior lights are out

-fuse box does not list “interior lighting”

 

The fuse is labeled “Dome” and is in the underhood fuse box. 7.5A

 

Do not see “dome”
Or, other possibles.
Thanks!
Maybe another fuse box?

 

Here's the interior cover for a 20, try the 10A for the dome and see if this helps. Also, what exterior lights are not working?

 

Well, dang, I guess I’m stuck in the past and assumed that even the later 2.5 gens kept the same basic electrical structure. Hopefully @TILLY ‘s help is more helpful.

 

Once I find it…
Easy to replace and assume it’s a bad fuse but
If there truly is a circuit fault it will blow again; maybe immediately.
I’ll buy several.

If it does blow again, I’ll inspect each lampholder and the door switch.
Try to look at the individual lamp switches.

Maybe pull all bulbs, replacing one at a time.

 

Are all the bulbs stock, or have you replaced any with LED?

 

Some are LED; replaced about 3 yrs ago

 

For some reason every time this topic comes up about blown fuses, it somehow always leads back to LED bulbs. Not sure why our trucks don't really tolerate them well. Another thing to look for is the connections on the light switches after installing new bulbs, they also seem to be fragile and come apart easily.

 

The dome fuse by the driver's kick panel is definitely the first place to look.

However, if that doesn't work, there are settings in the Entune system of your head unit that deal w/lighting under 'customization' that may have gone fubar on you for some reason

Here's a video that's a little hard to understand, but you can see the flow of menus to get to those settings in your head unit...

The 10A fuse above drivers L knee (wow, what a handy place) is blown.
Have purchased new ones but no further progress yet.

 

I’m mystified why switching to LEDs would cause a fuse to blow; way less power draw.

 

Normally a LED would draw less current but of there's a failure in the internal circuity all bets are off

 

Not saying your problem is definitely from the LED's, just that they have been with some members here. Let us know how you make out with this.

 

It is very easy to short the circuit and blow the fuse when installing led interior lights.
I've done it a few times, especially doing the visor vanity lights..

The odd thing in your situation is that they have been working for a while..

 

Map lights are notoriously fragile. Forcing an LED bulb into one of those if it isn’t going in properly has been known to short out the lights on one side or both sides. I believe there was a write up on here on how to fix / replace the housings in the overhead to mitigate this.

Also, I hate to be this guy but are the LEDs you’re using Amazon/ebay or are they from a more reputable company like VLEDS?

 

fuse changed, working fine for several hundred miles now

 

Lasted a few months then popped again; finally getting around to pulling all LEDs to retest with incandescents.
