      Diagnosis needs to start with the cooling fans. My first step would be to see if they energize when called for.
      most likely you will have to disassemble the fuse box to check the wiring from underneath.
      If yes check relay output for 12v. If yes continue your tree diagram up to the fan.
      if no clicky click at the relay check for called ground from the ecm. Follow tree diagnosis as called for.

      after the fans are repaired then start on diagnosis of AC system.
