Factory fog lights don't work.

The dash indicator says they are on but no lights. Also have the mod for the added reverse lights . They are LED that are connected through the harness for the trailer hitch. They don't work either. I didn't splice any wires used a splitter harness so i didn't have to cut any wires. Anyone else have this issue. I guess I should check fuses to see if any are bad.

Are the bulbs good?

As for your reverse lights, try swapping the wires, as LEDs are polarity specific, so if you have your positive and ground swapped, they won't work

The added reverse lights worked for years. Just wondering if it could be connected to the front fogs which I guess would be led also since the headlights are led. But I should check. Thanks

I didn't think fog lights and reverse lights would share a fuse, but fuses would definitely be something to check. After that, I'd check all the connectors to see if they are loose or maybe got corroded.

Fuses, poor grounds, problem with wiring harness and then the body control module that controls the lights.
