We have a vehicle that fan is blowing but little to nothing seems to be blowing out so the vehicle is not getting warm.
We have already replaced the heater core, resistor and thermostat. While we can hear the fan blowing and it seems to be stuck at the high level no matter which speed we choose, little to nothing is coming out. It is a warm temperature for the little that you can feel but in Illinois this will not be enough to defrost the windows. Any thoughts or help would be appreciated as we are a single income family and cannot afford a new car.
