Citroen C2 Overtemperature problem

Hello guys, 2004 model Citroen c2 1.4 I have gasoline vehicle.

There is an overheating problem in my vehicle that we cannot solve.

• Thermostat changed
• Sender changed
• Fan relay checked intact.
• No oil mixed with engine water. (seal intact)
• When I turn on the air conditioner, the fan is activated.

The fan sometimes turns on, there is no overheating problem in the vehicle, but sometimes it does not. When I travel with my vehicle very comfortably yesterday, when I go the same road the next day, my vehicle becomes overheated and I see that the fan does not turn on.

Do you have a problem, what should I do?

Hello, teacher. Well fan relays, socket cleaning etc. I looked at both. In addition, there is a fan resistance, it was checked.

I changed one fan relay. But I don't know where is the 2nd relay you mentioned. I haven't had the opportunity to change the fan residence yet, I guess it was his turn
