#15 has nothing to do with HVAC on Gen 2 Flexes based on manual.
#46 is for HVAC system. But I suspect that will not fix your issue fully.
Historically when any vehicles Resistor used for fan speed fails the fan gets full voltage and is on full speed. On the Flex the "reisistor for fan speed" is actually a circuit board and not an old style resistor.
