radiator fan

Did you use a voltage tester on fuses circuit, should be hot all the time. The fan should run if the ac is turned on. The coolant temp sensor can cause an issue. Is the engine overheating? What is the temp reading?

temp was 210 & fan didn't cycle test light showed circuit to be hot what about coolant fan switch

210 isn't very hot. Any applicable trouble codes? Some of the national brand autostores used to check codes for free. If you want to check codes yourself, at the least, you need an obd 2 code reaDER. To go further I'd have to check circuits at the fan relay/s.
