Check the fuses first as all of your warning lights are out it sounds like a main power supply problem.

Your entire concern centers around your Turn Signal/Multifunction Switch. If all of the fuses are good and power is supplied, I'd go there next. Try repeatedly switching the Hazard switch - it collects dirt and debris over time - the other thing that commonly happens the wires at the connector on the back of the switch break or come unplugged easily. Easy to pull the steering column cover and check.

The turn signals and hazards were not working on work van. I checked bulbs and fuses. I then repeatedly depressed hazard switch about 30 times and then turn signals and hazard flashers started to work.

I used the advice of 72mavrick (repeatedly depressing the hazard switch) and the turn signals began working.
