How to Buy a Good Quality Heater Blower Motor Resistor

Heater blower motor resistor

Vehicles that are equipped with a manual HVAC, or climate control, system utilize a blower motor resistor to control the speed of the heater blower. If you are driving a minivan or an SUV with a separate rear passenger climate control area, there is a good likelihood that you will have two of these items working in your vehicle at the same time.

Heater blower motor resistors are generally installed as a part of the heating, ventilation, and air-conditioning system to keep the air that flows through the HVAC system cooling down the resistor. The resistor generally fails because of foreign objects jamming the blower motor fan blade, which causes the resistor to overheat.

Replacing your current heater blower motor resistor can allow you more flexibility to ensure that the air blown through the motor is tightly controlled no matter the temperature outside your vehicle.

Here is some information about replacing a heater blower motor resistor:

  • Labor costs based on location: The cost of replacing your heater blower motor resistor is dependent not so much on the cost of the part, but more on the cost of getting to the part. Some vehicles may have the blower motor in plain sight in the glove box, while others may have it hidden further away, making it difficult and expensive to replace.

  • Meets OEM standards: All heater blower motor resistors should be engineered to meet or exceed original equipment manufacturer (OEM) standards.

  • Fan failure leads to resistor failure: You will often see failures on the heater blower motor resistor when the fan itself fails – hence overloading the blower motor resistor.

If you’re noticing that your heater blower motor is running more often than it should to keep your vehicle temperature regulated, then it’s time to have your heater blower motor resistor checked.
