The cost to replace a blower motor typically ranges from $200 to $600, while replacing the blower motor resistor usually costs between $100 and $300. Factors influencing the price include the make and model of the vehicle, labor rates, and whether you choose OEM or aftermarket parts. Comparing quotes and considering DIY options can help reduce the overall cost.
When your vehicle’s HVAC (heating, ventilation, and air conditioning) system starts to malfunction—whether it’s producing weak airflow, inconsistent fan speeds, or no airflow at all—it often points to issues with the blower motor or its resistor. These components are crucial for regulating the airflow inside your vehicle, ensuring you stay comfortable regardless of the weather.
If they fail, you might be faced with the decision to replace one or both. But how much should you expect to pay for this repair? This blog post will provide a detailed overview of the costs associated with replacing a blower motor and resistor, along with factors that influence these costs, and tips for saving money on repairs.

What Do the Blower Motor Do?
The blower motor is responsible for pushing air through the vehicle’s HVAC system and into the cabin. Whether you’re looking to cool down with air conditioning or warm up with the heater, the blower motor is what drives the air through the vents. It operates at various speeds, depending on the setting you choose on your HVAC controls.
What Do the Blower Motor Resistor Do?
The blower motor resistor is an electrical component that regulates the speed of the blower motor. It does this by varying the amount of current that reaches the motor. At lower fan speeds, the resistor adds more resistance, reducing the current and slowing down the motor. Conversely, at higher speeds, the resistor reduces resistance, allowing more current to flow and increasing the motor’s speed.
Symptoms of a Failing Blower Motor or Resistor
Before diving into the costs, it’s important to recognize the symptoms of blower motor or resistor failing. Common signs include:
- No airflow from the vents even when the fan is turned on.
- Weak or inconsistent airflow, particularly when set at lower speeds.
- The fan only works at certain speeds, often just the highest.
- Overheating of the HVAC system, which may be accompanied by a burning smell.
If you notice any of these symptoms, it’s likely that your blower motor or resistor needs to be replaced.
Average Costs of Blower Motor and Resistor Replacement
The cost to replace a blower motor or resistor can vary significantly depending on several factors, including the make and model of your vehicle, the type of parts used, and labor costs. Below is a breakdown of what you can typically expect to pay.
1. Blower Motor Replacement Cost
The cost of replacing a blower motor usually ranges between $200 and $600. This price includes both the cost of the part and labor.
- Part Cost: The blower motor itself typically costs between $50 and $300. The price varies based on the brand, the quality of the part, and whether it’s an OEM (Original Equipment Manufacturer) or aftermarket part. OEM parts are generally more expensive but are often recommended for better compatibility and longevity.
- Labor Cost: Labor costs for replacing a blower motor usually range from $100 to $300. The time required for replacement can vary depending on the complexity of the vehicle’s HVAC system and the location of the blower motor. In some vehicles, the motor is relatively easy to access, while in others, it may require more extensive disassembly of the dashboard, increasing labor time and cost.
2. Blower Motor Resistor Replacement Cost
Replacing a blower motor resistor is generally less expensive than replacing the motor itself, with total costs ranging from $100 to $300.
- Part Cost: The resistor part typically costs between $20 and $100. Like the blower motor, the price depends on whether you opt for an OEM or aftermarket part, with OEM parts usually costing more.
- Labor Cost: Labor costs for replacing a blower motor resistor are usually between $50 and $150. The resistor is often easier to access than the blower motor, meaning the replacement process is quicker and less labor-intensive.
Factors Influencing the Replacement Cost
Several factors can influence the overall cost of replacing a blower motor or resistor:
1. Make and Model of the Vehicle
The make and model of your vehicle play a significant role in determining the cost of replacement. Luxury or high-end vehicles typically have more complex HVAC systems, which can make parts more expensive and increase labor time. Additionally, vehicles from certain manufacturers may have parts that are more expensive or harder to find, further driving up the cost.
2. Location of the Blower Motor and Resistor
In some vehicles, the blower motor and resistor are located in easily accessible areas, such as under the dashboard on the passenger side. In other vehicles, these components may be more difficult to reach, requiring the removal of multiple components or even parts of the dashboard. The more complicated the access, the higher the labor cost.
3. Type of Parts: OEM vs. Aftermarket
Choosing between OEM and aftermarket parts can also affect the overall cost. OEM parts are made by the vehicle’s manufacturer or a contracted company and are typically designed to match the original parts’ specifications exactly. They tend to be more expensive but are often considered more reliable.
Aftermarket parts, on the other hand, are produced by third-party manufacturers and can vary in quality and price. While some aftermarket parts are just as good as OEM, others may not fit as well or last as long, which could lead to additional costs down the line.
4. Geographic Location
Labor rates can vary widely depending on where you live. In urban areas or regions with a high cost of living, you can expect to pay more for labor than in rural areas. Additionally, the availability of parts may vary by location, potentially impacting the cost if parts need to be specially ordered.
5. Repair Shop Rates
Different repair shops have different labor rates. Dealerships often charge higher rates than independent mechanics, but they may also have better access to OEM parts and specialized knowledge of your vehicle. Independent shops may offer lower rates and more flexibility with part options but could vary in the quality of service.
How to Save on Blower Motor and Resistor Replacement
While replacing a blower motor or resistor can be costly, there are ways to potentially save money:
1. Compare Quotes
Don’t settle for the first quote you receive. It’s a good idea to shop around and compare prices from different repair shops, including dealerships and independent mechanics. This can help you find a competitive rate.
2. Consider Aftermarket Parts
If cost is a major concern, consider using high-quality aftermarket parts instead of OEM. Make sure to choose parts from reputable manufacturers to avoid potential issues with fit and durability.
3. DIY Replacement
For those with mechanical experience, replacing a blower motor or resistor yourself can save on labor costs. However, this approach requires the right tools and knowledge, as incorrect installation can lead to further damage. Be sure to consult your vehicle’s repair manual and, if necessary, seek out tutorials or guides specific to your car’s make and model.
4. Regular Maintenance
Preventative maintenance can help extend the life of your blower motor and resistor. Regularly replacing the cabin air filter and keeping the HVAC system clean can reduce the strain on these components, potentially delaying the need for replacement.
5. Warranty Coverage
Check if your vehicle is still under warranty, as the replacement of the blower motor or resistor might be covered. Some extended warranties or service plans may also include coverage for these repairs, which can significantly reduce your out-of-pocket expenses.
Conclusion
Replacing a blower motor or resistor can be an unexpected expense, but understanding the factors that influence the cost can help you budget more effectively and make informed decisions. Whether you choose to go through a dealership, an independent mechanic, or attempt a DIY fix, it’s important to weigh the cost against the quality and reliability of the parts and service you receive. Regular maintenance and early detection of issues can also play a crucial role in minimizing repair costs over the life of your vehicle. By staying informed and proactive, you can keep your HVAC system running smoothly and ensure that your vehicle remains comfortable year-round.
