Take off the front light cover, and check this wire right here. I had the same problem and for me this wire came loose. It was even covered in glue and everything, its as if it wasn’t plugged in all the way at the factory, or something. In anycase, this was the problem, and its hidden behind the LED light defuser, the what cover the covers the light. It just pops off, no screws or clips, it pulls straight off, then check this connector.
