Depends on the radiator! Usually there's a temperature switch screwed into the rad somewhere (often at top left-hand side). The switch should close when hot, causing the fan relay(s) to activate the fan(s).
It may be a burned-out relay, rather than the switch...

If the switch is in the top n/s corner of the rad., I've always found that you can access it by removing the headlamp and the pod. If you remove the two otter switch leads from the switch and connect them together temporarily, with the ignition on, and the fan activates, then you have a duff switch.
