If it doesn t light up or you only have a high fan speed then your resistor block needs replacement since it is bypassed on high speed.
Car heater fan only runs on high.
You tried turning on the ac and the different climate controls and it s the same.
Though having only one fan speed usually indicates a bad blower resistor a diligent mechanic at a repair shop will test the resistor fan switch and connections to the motor to make sure nothing.
If the resistor block tests out good and you don t have any fan speed or a slow fan speed for all speeds you can assume that the blower motor is at fault since everything else has tested out ok.
