Could you be more specific about which cooling fan relay you're testing at? Here's the diagram:
It looks like the PCM controls the LOW relay to command both fans on at low speed, and controls the LOW and HIGH relays to get high speed. Are you seeing no power, or no ground at either relay?

through your diagram I recognize the problem is from the PWR TRN relay
