My led lights under the footwells both just stopped one day. I check all the fuses and they seem fine. It was factory installed and I am stuck. The wiring is fine. What can I do. Any help would be appreciated. It is a 2018 Hyundai Elantra.
The fuses 'seem' fine? Did you swap with known good or check them for continuity?
How did you check the wiring? A volt meter would be the best way to see if power is getting there.
2018 might still be under warranty and that's who I would let fix it if it is.
