I have suddenly noticed that my electric radiator fan is not coming on at all. Fuses are OK and the fan does work when independently powered I am suspicious of the fan relay but worried about the ECU influence. Strangely enough the temp gauge, even in hot conditions, shows a normal reading. I also have a lack of cold air from the Climate control but that could be an unconnected problem. Anybody got any ideas or checks I can make to trace this problem(s)
