Indicators not working.

[DesH]

Hi folks.
I have an 05 transit T350 mwb.
Yesterday the indicators (both sides) packed up.
All indicators and repeaters are working with the hazard switch and the remote fob. I've switched out the indicator stalk, relay above brake pedal, hazard switch and two relays under expansion bottle. I found a corroded red wire under the aux fusebox on inner wing which I repaired, but still no joy. Oh, and I've replaced fuse 205 and 226 from the fusebox under passenger tray. Those were the only indicator fuses I could find reference on.
Any advice would be greatly appreciated.
