Fiat Doblo motor failure

Hello! I have a Fiat Doblo. The engine began to give me problems. It goes quite well in cold, but when the engine is heated. The strange thing is that when it is hot, but in the early morning I don't give me any problem. See if someone does a hand?

The car is diesel or gasoline and what engine has

The engine it carries is 1.9d in 2001. I find the electric schemes and I think it can be from the refrigerant sensor.

Hello with this data I cannot help you is a 1.9 aspirate or it is a 1.9 jtd that makes you for you to say that it is the refrigerant sensor explain a little more the game if the engine you have is the one that I tell you greetings Alf.-

Hello! It is an aspirated engine. I think it is the sensor, because the fan shoots by the control of the switchboard. And for that the switchboard receives signals from the refrigerant temperature sensor and air conditioning system. What I saw is that the fan and the relays are not triggered. That's why I think it can be the sensor.
SATURDAY CHANGE IT AND I WILL ALREADY TAKE YOU MORE THINGS. Thanks Alf!
