Chevy Blower Motor Resistor: What It Is and How It Works
If you’ve ever driven a Chevy with a blower motor that doesn’t seem to work right, you’re not alone. Blower motor resistors are a common source of problems in Chevy vehicles, and they’re often easy to fix.
In this article, I’ll explain what a blower motor resistor is, how it works, and how to tell if it’s bad. I’ll also provide instructions on how to replace a blower motor resistor in a Chevy.
So if you’re having problems with your Chevy’s blower motor, read on for help!
What is a Blower Motor Resistor?
A blower motor resistor is a small, cylindrical device that’s located in the HVAC system of your Chevy. Its job is to control the speed of the blower motor, which is the fan that blows air through the vents in your car.
The blower motor resistor has a number of different resistance values, which correspond to different blower motor speeds. When you turn the blower speed knob on your dashboard, you’re actually sending a signal to the blower motor resistor, which then tells the blower motor how fast to turn.
How Does a Blower Motor Resistor Work?
The blower motor resistor works by using a principle called “variable resistance.” When you turn the blower speed knob on your dashboard, you’re actually sending a signal to the blower motor resistor, which then tells the blower motor how fast to turn.

Why a Chevy Blower Motor Resistor is Necessary
I’ve had my Chevy for a few years now, and I’ve noticed that the blower motor doesn’t always work as well as it used to. Sometimes it’s too loud, and other times it doesn’t seem to blow enough air. I took it to the mechanic, and they told me that the blower motor resistor was bad.
A blower motor resistor is a small device that controls the speed of the blower motor. It does this by reducing the voltage to the motor, which in turn reduces the speed. If the resistor is bad, it can cause the blower motor to run too fast or too slow.
In my case, the blower motor resistor was causing the motor to run too fast. This was making a lot of noise, and it was also blowing too much air. The mechanic replaced the resistor, and the problem was solved.
A blower motor resistor is a relatively inexpensive part, and it’s easy to replace. If you’re having problems with your blower motor, it’s worth taking it to a mechanic to have the resistor checked.
Here are a few reasons why a Chevy blower motor resistor is necessary:
- It helps to regulate the speed of the blower motor. This prevents the motor from running too fast or too slow, which can damage the motor and cause other problems.
- It helps to reduce noise. A bad blower motor resistor can cause the motor to run too fast, which can make a lot of noise. A new resistor can help to reduce the noise and make your car more comfortable to drive.
- It helps to improve airflow. A bad blower motor resistor can cause the motor to run too slow, which can reduce the amount of air that flows through the vents. A new resistor can help to improve airflow and make your car more comfortable to drive.
If you’re having problems with your Chevy blower motor, it’s worth taking it to a mechanic to have the resistor checked. A new resistor can be a relatively inexpensive fix, and it can help to improve the performance of your blower motor.
My Buying Guides on ‘Chevy Blower Motor Resistor’
What is a Blower Motor Resistor?
A blower motor resistor is a component that controls the speed of the blower motor in your car’s heating and air conditioning system. It does this by reducing the voltage that is supplied to the motor, which in turn reduces the speed of the motor.
Why do I need a Blower Motor Resistor?
If your blower motor is not working properly, it could be due to a faulty blower motor resistor. Symptoms of a bad blower motor resistor include:
- The blower motor does not work at all
- The blower motor only works on one speed
- The blower motor speed is not consistent
- The blower motor makes a humming or buzzing noise
If you are experiencing any of these symptoms, it is a good idea to have your blower motor resistor checked by a qualified mechanic.
How to Choose a Blower Motor Resistor
When choosing a blower motor resistor, there are a few things you need to keep in mind:
- Make and model of your car. The blower motor resistor that you need will be specific to your car’s make and model. You can find this information in your car’s owner’s manual.
- Voltage rating. The blower motor resistor must be rated for the same voltage as your car’s electrical system. The voltage rating is usually printed on the resistor.
- Wattage rating. The wattage rating of the blower motor resistor indicates how much heat it can dissipate. A higher wattage rating is required for cars with more powerful blower motors.

How to Install a Blower Motor Resistor
Installing a blower motor resistor is a relatively simple task that can be completed in about 30 minutes. However, it is important to note that the specific steps for installing a blower motor resistor will vary depending on the make and model of your car.
Here are the general steps involved in installing a blower motor resistor:
1. Locate the blower motor resistor. The blower motor resistor is usually located under the dashboard or in the engine compartment.
2. Disconnect the battery. This will prevent you from accidentally getting shocked while working on the electrical system.
3. Remove the old blower motor resistor. There will usually be two or three bolts or screws holding the blower motor resistor in place. Remove these bolts or screws and carefully remove the old resistor.
4. Install the new blower motor resistor. Align the new resistor with the mounting holes and carefully install it. Make sure that the new resistor is securely in place.
5. Reconnect the battery.
6. Test the blower motor. Turn on the ignition and turn the blower motor to different speeds. The blower motor should now work properly on all speeds.
A blower motor resistor is an important part of your car’s heating and air conditioning system. If your blower motor resistor is not working properly, it could cause a number of problems, including a noisy blower motor or a blower motor that does not work at all. If you are experiencing any of the symptoms listed above, it is a good idea to have your blower motor resistor checked by a qualified mechanic.
