I'd still pull the switchgear off the bars and take a look. The hazard switch and indicator switch wiring are interconnected in the switch assembly. You will need to trace the single GREEN wire from inside the switch all the way to the connector where it splits into a front and rear separate feed. If both front and rear right hand indicators are dodgy, the fault can only be within this shortish section of green wire. Any problem after this connector will only cause trouble with either front or rear, but not both.
