The most common symptom of a bad blower motor resistor is that you will only notice that your blower is working on the highest speed setting or that it won't work at all. The main symptoms of a bad blower motor resistor include: Only One Speed From Blower Motor. Various Airflow Settings Not Working.The blower motor resistor is designed to last till the end of the car’s lifespan. However, due to multiple reasons, they tend to get damaged before. If you have a faulty blower motor resistor in your vehicle, it’s best to replace it immediately.
Do you need to replace blower motor resistor?
If you're unable to use all the settings and only a handful work, it could be because of a faulty blower resistor. The blower resistor controls the power to the motor, so when the resistor goes out, the air will not come out of the vents.
When should I replace my blower motor resistor?
The most common symptom of a faulty resistor is that the blower motor only works on one speed with the HVAC controls and it's inoperative on all other speeds.
What happens when a blower motor resistor fails?
If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. The heating and air conditioning systems may still function at one speed, however the resistor will have to be replaced in order for full functionality to be restored.

What is a blower motor resistor?
The motor that runs the fan in the heating and air conditioning system in a car is called a blower motor. It's located inside the dash, often on the opposite side of the steering wheel or inside the engine compartment on the firewall. A blower motor resistor or a blower motor control module is the part that controls the speed of the blower motor.
Can a blower motor resistor cause a heater fan not work?
Problems with a blower motor resistor are common in many cars. The most common symptom of a failed blower motor resistor is when the heater fan only runs at high speed and doesn't work at low speeds. In some cars, a failed blower motor resistor can cause a heater fan to stop working completely.
How do I know if my blower motor resistor is bad?
Let’s begin with a look at the signs to look for.
