All interior lights stopped working

My wife was checking the mirror behind the visor and the lights didn’t come on. I thought it was strange so I tried the dome lights. Nope. Map lights? Nope. What’s going on with it? As far as I can tell I might have blown a fuse but i can’t check that until tomorrow. Just curious if there is any other ideas floating around out there. I thank you all in advance for any advice.

 

There are some harness plugs above the headliner behind the overhead console.

 

fuse sounds like a good bet if all those lights dont work.

 

Did this start after mods to dash?
If so, try unplugging all that, and recheck. Mods always a good place to start.

 

If you did ANY jacking around with the electrical system, start there. Fuses blow for a reason.

The only mod to the dash was the DMM from The Taco Garage. Nothing to the electrical there.

I dug that up this morning when I finally got around. I was able to identify that it was, in fact, the fuse. I replaced it and BOOM, like magic, everything works again. If this happens again I will take it to Toyota for a look-see. There was no change to the electrical system inside the vehicle. The only "mod" that had anything to do with power was when I had the ARE cap installed and they wired in the brake light and the LEDs in the cap itself. All of that appears to have been wired from the battery and not tied into the existing wiring. I don't know. We shall find out if it was a fluke or faulty fuse or something more sinister!!! LOL

Also, a big thank you to anyone who's commented and helped guide me into the right direction.

Thanks!
