Short to ground. Please help!

What do you mean "flashers?" And what do you mean "short to ground?" How did you determine this? EG If you checked from the lamps to ground they WILL suggest a short, as just one stop/ turn lamp filament is very low resistance.

If you are saying that the hazards operate and the turn signals do not, they actually use the same lamps, so they can't be shorted, UNLESS something in the switch is shorting them when the switch is centered

We need to know exactly what works and what does not and what lead you to the conclusion
