Here is diagram:
The above diagrams are for unit with manual ac/heater controls. If yours has automatic ac/heater control unit, then it doesnt have a resistor. It will however have a fan motor control amplifier shown below:
You may need the amplifier or a control unit. Does yours have navigation system so that I can give you testing procedure so that you can replace the correct part
The most likely problem is the fan control motor amplifier. If you have access to a DVOM(digital volt/ohm meter) there are a couple of tests to do to confirm if this is faulty. As expensive as parts are for today's vehicles, I am a firm believer in testing before making any assumption on a part being faulty. The fan control motor amp basically serves the same purpose as a resistor.
Here are tests to perform.
