Dumb question, but I'm going to ask it......have you checked the bulbs?

The wiring will most likely be run in the wall behind the front cap. It's possible they go up the sidewall from the lower marker light and then across the front. If you have checked the bulbs and it s definitely a wiring issue, I would suggest dropping the underbelly below the marker light and check the connection where it goes up from the main harness. The three lights are probably all run off of the same pigtail.
