I have the symptom where my heater fan only blows on high and I've read the solution concerning the switch and resistor pack. However, I still have a question to help determine if it is the switch or the resistor pack.
My fan behaves this way. If the switch is set to the lower settings, then the fan does nothing. If I set the switch to high, then the fan comes on and blows at high speed.
If the resistor pack is bad, does the fan blow at high speed no matter what setting the switch is at or does it cause the behavior that I mentioned above?
Thanks.
