As far as the radiator fan, check fuse2--40 amp in the underhood fuse block. Check the coolant temp sensor.

for the heater blower, did you check applicable fuses and voltage? The resistor block and hvac control are on the ground circuit. Did you check voltage and ground at the blower motor connector?
