engine twin electric fans stay on.

[Raybould]

I have a 1997 hymer Fiat ducato engine. I have replaced both sensor switches Radiator/Engine but the fan stays on until unplugged.
I am assuming there is a relay involved. Does anyone know where the relay is . Thanks

Yes there will be a relay, and possibly more than one. There is two in the later 250 Ducato, and they are in the under bonnet fuse box.
Sorry can’t help with the earlier Ducato location.

Some engines the fan stays on as part of the DPF/regeneration process, might be a time to (dirty words warning) !!!
Read the handbook!

If memory serves the relays are on the radiator between the fans at the top facing the engine

Seems to me the relays are shorted out / full of water which happens
