I am ashamed to ask this as I am a car guy
But where the heck is the interior lights fuse?
Was installing leds and they all went out
Thanks

Do you mean the dome lights or the inside backlighting? The backlighting is all through the taillamp fuse and relay, it's a 10A in the IPDM (RH rear of the engine box). The dome lamps go through the BCM but are fused upstream from it, it's a 10A fuse in the interior fusebox at the left end of the dash.

Interior dome lights, map lights, door jamb lights, under dash lights etc all went out

Is it the one marked room lamp on the interior fuse box?

Why the heck don't they just call it interior dome lights

Thanks

Yep and beats me, in that order.
You're most welcome.

Thanks

Pulled the room lamp fuse, it was toast

Popped in new one, good to go

Thanks

When doing anything electrical on an Infiniti, especially something seemingly as innocuous as changing interior bulbs to LEDs - I would disconnect the negative terminal on the battery. I blew out a BCM changing some bulbs on my '13 M37 and I'm pretty sure another member on here did too - maybe Ilya??
I removed the LED bulb while it was still under warranty and brought it to the dealer because all of my interior lights went out and none of my fuses had blown...could've been a hard lesson learned.

Good advice. Most people don't realize that interior lamps aren't just switches and bulbs anymore, the fancy "fade out" after the doors close and handy Power Saver that prevents an open door from trashing your battery both mean one thing: The BCM has to be in charge and not a switch. The transistor drivers aren't weak, but like any semiconductor in a car, they can be easily "popped" by overvoltage from careless sparks. Better safe than sorry!

Whelp. I think I’m that guy… I checked a few fuses and they looked fine. But, basically my dome lights won’t turn on when the doors open now… I did install new LED lights… and of course I didn’t unplug the battery... but I can turn them on manually. I also smelt burning.

BCM need to be replaced now? I don’t know what else to try.

Yep, if they'll turn on manually then the power side of the circuit is good but the ground leg connecting to the BCM either has a burnt wire/connector or the BCM itself has a blown transistor.

What would y’all do?

I have had no interior lights for 2 years, when you open the door. They do work when you press the button manually. Can you post a pic of the fuse you replaced to make them work. I have gone through all the fuses in the driverside floorboard area and engine compartment with no luck. I did buy a VIN specific BCM but it did not work as I think the harness is fried too maybe. But if its a simple fuse, that will be amazing.
TIA

I believe this is the part# 24013 1MA0A
