Hi guys,

I have got problem with my radiator fan on Fiat Doblo 1.3. Sometimes it just start running when I drive and will not stop until I turn key off. I do not know what it is.
Could you please help me.

My thoughts are:
Could be relay or contact or water pump switch? Anything else?

Thank you.

Does you Doblo have Air Con?

It could be you have inadvertantly switched it on (push the fan speed switch inwards on the dash) and this automatically activates the cooling fan.

Either that or the coolant temp switch that activates the cooling fan is faulty.

There is no air con.
How do you mean : (push the fan speed switch inwards on the dash)??
I was in garage when this happened but they do not know, says maybe a switch on water pump but not sure.
Thank you

If the vehicle has AC, the fan switch can be pushed in to activate the AC.

If not, don't worry about it.

I should think the switch that activates the fan has packed in and the fan now cuts in by default as a safety measure.

If you are not sure what to do, best go to a garage and have it checked as these vehicles are fitted with multiplex wiring.

Hi

Thank you very much for your help. I will do even I have tried it but need to find another garage.

Thank you again.
