A Failed Heater Blower Motor Resistor at James Aldridge blog

A Failed Heater Blower Motor Resistor. Blower motor fan only works in. The blower motor fan only works in certain speeds. The heater resistor is also known as the heater blower motor resistor or blower speed controller because it fundamentally controls the fan speed of the interior heater. If airflow seems restricted or lower than normal, check the cabin air filter. If you can’t defrost your windshield, or warm up or cool down your car, a bad heater blower motor resistor can make it difficult to drive safely or comfortably. Check for full airflow at the vents. If the blower motor resistor is bad, your blower motor can get stuck on a single speed. Here are some of the most common signs that the blower motor resistor has failed in your vehicle: The blower motor resistor has repeat failures. The most common symptom of a failed blower motor resistor is when the heater fan only runs at the highest speed setting (4 or 5). There could also be various airflow. If you’ve replaced a blower motor resistor and that replacement has failed, it’s time to conduct an amperage test on the blower motor. Decreased airflow causes the blower motor resistor to overheat and fail. If you’re no longer able to regulate the speed of the blower motor, the vehicle may have a failed heater resistor. If it’s good, check for debris on the evaporator or heater.

If the amp draw exceeds the manufacturer’s. The blower motor resistor has repeat failures. If it’s good, check for debris on the evaporator or heater. Check for full airflow at the vents.
