    Given the paperclip test you ran, it seems like the load side (at least from the switch to the fans) is OK. I would start looking at the control side using a wiring diagram and live data. Not real familiar with hondas, but I would check that the coolant temp is being read correctly by the ECM and the see if the signal is sent to close the fan relay. IF that is good, you just need to chase it down the load side to wee where the continuity is lost.

    Good Luck.
