Hi . First i want to congratulate for this forum. This is my issue. I have a 2004 scenic 1.6 16v. The radiator fan starts even when i m running in the motorway although the water temperature is ok.It stops briefly then it starts again. it always works in full speed (Such as when a/c is on). Some times when i m stopped in red light, it"s speed fluctuates. When i stop the engine, it stops too and the next morning when i turn the engine on, the fan starts too (such as it keeps going from last night) and stops in a while. I ve been in the garage . I ve changed the resistance and the bubble i even changed the cabin cpu but the problem still goes on. The thermostat seems to work regular.All these happen when a/c is off. any proposals are welcome. Thank you.
