Inside A/C Heater Fan not working all others function normal

I don't expect any B or body codes to be present. However, your fan inside the vehicle is dependent upon a blower speed controller or a resistor that controls fan speed working properly, or a blower motor and wiring issue itself. Hands-on testing by somebody who knows what they're looking for rather than "retrieving trouble codes" would be quite helpful.
