Blinkers not working on 2006 Toyota Tundra

While driving today the blinkers stopped working. There is no sound or flashing on the dash board. The hazzards work. I have checked the fuses and can't find any that are blown. I did town my trailer today and it happened while I was towing but I am not sure if that has anything to do with it.
