Hello,
This sounds to me like you could possibly have a short to ground on the ground wire from pin #47 of the Engine Control Module (ECM) to the Control Side of the Cooling Fan Relay Connector pin #C1. I have included a description of the engine cooling fan circuit as well as your vehicle's cooling fan circuit in the diagrams down below. I have hi lighted the wire to check for you, it is the dark green wire. Look for bare wire that is grounding out or damaged insulation. Please get back to us with what you are able to find out, please.
Thanks,
Alex
