No tail lights, no left blinker. Hazards work and brake lights work.

What is your question?

Anyone know what could be wrong? My tail lights and left blinkers do not work. But the hazards and the brake lights are working just fine. Any ideas? I had this pickup for about 5 months now. The left blinkers never worked. Now about 1-2 weeks ago the tail lights just stopped working. I got new bulbs and new fuses, still nothing. Also I replaced the light switch and still nothing.
