No check engine light, throws no codes, does not over heat, but the fans won't stop running. Has anyone experienced anything like this before?

 

First check the temperature sensor on the engine.

 

Thank you for the reply oldchevy. I checked the relays and they weren't the problem. I installed a battery disconnect in the meantime to get me by til the weekend. I was hoping that if the coolant sensor was bad that it would throw a code or check engine light would come on. I'm guessing that's not the case, because of your reply. Guess I know what I'm doing tomorrow.
Any other feedback or tips would be very appreciated and thank you again.

 

Changed the temp/sen and problem solved. Sorry for the lack of haste in my update. Still confused on why the bad sensor wouldn't throw a code
