How hot does the engine get in degrees F? The low speed fan comes on about 223 degrees F, the high speed comes on about 230 degrees F. Also, when you turn on ac, the fans may take off. Did you check voltage and ground at the fan/s wiring connector for the fan that doesn't work?

Check for combustion gases in the coolant?
