Normally I would say if you have a mix of led and "normal" indicators hazards won't work if you still have the standard indicator relay and sometimes the front and rear may do the same thing.
But you say they all worked fine prior and now one side not working, hazards not working and one side intermittant.
Check all connections are pushed in tight (located under riders seat on rhs (as sat on the bike) if the fuse is all good the only other thing is a cable has been broken (or was already broken and any moving of them has disturbed what connection there was)
You can get aftermarket oem indicator connectors with bullet connectors for plugging in after marked indicators to the bikes loom (negates the need to cut the wiring loom up) , but if the break in wires is on the indicator side its either a repair ore replacement indicator.
Ideally a pic of the indicator wiring would be best, especially of any joins in the wiring.
