Hi, I'm new to this forum. I have a '96 4runner, and ran into a bit of a problem today while swapping out my map lights with new LED panels. I might have shorted something during the install because the automatic door locks, radio, interior lights all went out at the same time and haven't came back on since, even after I removed the new lights. I can't toggle the door locks from my remote or from the door panel control. Turning the key only unlocks that particular door instead of all four. I can toggle the alarm, but it is acting sort of funny - when I turn it on and off it will emit four chirps; it's never done this before.

Everything was working fine prior to my attempt at doing the LED swap. My dash lights, AC, windows, etc all work. As far as I know, the problem is only restricted to the interior lights, radio and door locks.

Has anyone seen this problem before? Could it be a blown fuse or a relay? If so, which one? What should I look for?

Check for a fuse in the engine compartment fuse box. It's called "DOME", 10A.

Well that was fast -- it was the dome light fuse! Swapped it out and everything came back on. Thanks!

I was gearing up for a much more complicated check, looking up wiring diagrams and such. Nope, just one fuse disabled all of those systems.

I'm having the same issue, but the Dome fuse isn't blown. I also checked the Accessory fuse, same deal.

The only thing is that I replaced both fuses and after a couple days, both fuses have a bit of reddish tint on the pins. Any idea what that could indicate?
