can somebody tell me why my rad fan never stops running. From the second i flip the ignition to on the fan runs and never stops. Its not a huge problem since all its gonna do is keep the car cool but i would like to know why?

Thanks
 
Probably a sticking relay. Try tapping on the IRCM (the square box in front of the air cleaner) with a hammer and see if it stops. If it doesn't, I'd pull codes to see if the EEC thinks the car is hot and is trying to turn the fan on. Could be a bad sensor.
 
please dont hit the ircm

it may ruin it try temp sensor also check connection if pin 14 has bad connection it will turn on fan
 
I wouldn't mess with it, your engine needs to stay cool.

Maybe the previous owner wired it into the ignition to stop cooling problems..
