Which Relay to change?

Can anyone tell me which relay that is the one that controls the indicators on a 1995 Iveco Eurocargo. I have no way of testing them, but the indicators are staying on, with the beeping noise but not flashing!
I have change the stearing control stock, the hazard flasher button/ unit and now I need to find the relay.
Thanks for any assistance.
