None of the interior lights turn on anymore
I was trying to upgrade all the lights to LED and I got all of them but the rear seat lights. They were all working until i took the bulb out. Then i tried to turn the rest of them on and none of the lights turned on.

I got no clue how this happened and if someone could help me fix this id really appreciate it, thanks!

All those lights are managed by the Body Control Module.

Have you tried putting at least some of the original bulbs back in.

I don't know why people always have to try to modify factory engineering. It is far more sophisticated these days than anyone is expecting.

Thanks for the response! I didnt have the right size so the back seat lights are still the factory bulbs. Anything else I should try?

At this point you are just going to have to systematically follow a wiring diagram to test the circuit. You will likely need a professional level scan tool capable of accessing the BCM to see the status of these circuits.

Start out by testing for power and ground at the sockets that aren't working.

Put all the OE bulbs back? If still a no go it blew something hopefully just a fuse that may look fine, test it with a test light, Tom
