i dont think my fan is kicking on. is there a relay onthese or anything? my temp has been up n down , never to warm just warmer then usual always drops down tho when i get out and cruise. is there a way to test these to see if its kicking on? do i just unplug it and hook 12v up to it and gound it?

 

if u just put 12v to it it would never turn off no matter what

 

well this is what im asking how can i test it?

 

turn your defrost on and it should kick on. if it doesnt. then try 12v to it
