Technical Radiator fan staying on

[allan jenkins]

Another question fellas.
My radiator fan seems to be on all the time.
Before when the car was idling the fan would kick in every 30 seconds or so then go off and back on.
Now it seems to be on constantly.
What do you think could be the problem.
I know at the moment it's 35° here in Wales but I still don't think it's right as there is a lot of hot air blowing out the drivers side wings.
Cheers for any help

Do you mean radiator inside the car or the cooler with bigger fan in the front of the car?
If it is the larger fan in engine, if you turn AC on, it will get running everytime. Especially in this weather. It has the second - faster - speed which is on when the engine is runing hot.

Hi, Don't suppose you could help me, I know that when i turn the ac on the radiator fan runs, but it doesn't seem to have a lower speed setting that i've seen? Does it always run on high speed with the AC or does it depend on conditions?
Thanks
