Testing fan relay switch

[nicoalex2]

How can you check if your fan relay switch is working?? My radiator fan is not turning on and I want to check that first.

I am not sure on the relay swiches but you can test the fan directly by hot wire it directly to your fan. it it does not work then your fan is the problem. If it does work then your problem may or may not be due to the relay. you may have to test to see if you are getting voltage to your relay. Check also your fan fuse..

fans also turn on when the engine is running at a normal idle check a temp sensor
