Right indicator (all three) not working, dashboard indicator mostly blinking very quickly and/or irregularly

I have an intermittent problem with right side blinkers:
- Dashboard indicator most of the times now flashing very rapidly and irregularly, blinkers themselves not working.
- Replaced bulbs and checked wiring: no change.
- Problem appears with alarm switch as well (i.E. Not just when using he switch on steering wheel).

So, I am thinking it is "something" on the MFE board, do you agree? If so, should I get the relays changed or is there a way to deduct whether it is that or the controller?
