It sounds like you've replaced everything. When you say resister, are you referring to the fan control amplifier at the lower right side of the dash?
If so, then we need to check for either a power loss or a ground-related issue. The fan motor gets power directly and then it routes it through the amplifier which signals voltage to the controller.
Before I can dig into the schematics, I need to know if the vehicle has automatic climate control or manual control.
Let me know.
