The thermostat on the bottom of the radiator is not working, so I have unplugged it and rewired it so that the fan is permenantly on whilst the car is running. It was working fine like this but now has stopped and I can't get the fan to work at all. Pulled the wire out and there is a clicking from the relay when i plugged it back in, so I have replaced the relay but it is clicking. So not sure what to try now...any suggestions? Cheers
