I don't know if there is some sort of relay near the fan, but I had a Jeep Grand Cherokee that was doing the same thing. It was the relay that was located on the inner fender. I had to cut out a piece of the front bumper cover, which luckily was not visible when everything was reassembled. Had to remove the battery cable to keep from completely discharging the battery.
