THe fan for my radiator decided to take a sh*t on me so I ran a wire from the battery to the fan and grounded the other end, the fan started so I know thats still good but I think the relay is bad. Is their any way to test a relay or is my best bet to buy a new one and test it that way?

Thanks.

 

To test it, apply power to it and if it doesn't make a click sound, it's bad... if it makes a click, you need to verify that the contacts are clean/good... check this out: http://www.autoshop101.com/tra....html
