Technical Radiator Fan Do Not STOP (2.8 IdTD)

[Nunooli]

Hello everybody. Radiator fan do not stop, ducato Campervan, 2.8 IdTD (2001).
I've changed the bottom thermal switch. The problem stills there.
No idea about where is the rele.
Any Help?

I have read that fan relays are in a box at the top of the radiator, and that one of the fans runs if the air conditioning is switched on.

Hope that this helps.

Thanks a lot. I continue to looking for the box without success. And I have no AC.. so must be the relay stacked... I guess

is it not possible that a bypass switch has been fitted somewhere in the cab maybe bottom of the dash and has been accidently switched on ?? maybe fitted by a previous owner. should be possible to trace from fusebox.
