with my bike, the hazard switch died which meant no indicators. Temporarily fixed with wire shorting out the relevant terminals.
Do all lights work, stop and tail lights, horn? instrument lights.
It's odd for a switch to fail in both directions, but not impossible.
If you have a multimeter with ohms and a wiring diagram, you can disconnect the plugs under the tank and check the switch out, quite simple.
Also switch to volts and look for volts on these plugs.
Let us know what year your bike is, is an LS or not? this helps us show you wiring diagrams.
