Enjoy correct driving temperature with a new blower motor in place of your beaten stock.
Bet you've thought about your car's air freshener far more often than your car's blower motor-one of those parts that some car owners realize they have only when it has broken down. And what happens when this motor breaks down? Nothing really, except that you might as well put an electric fan in front of your car's air con vent just so cool air would reach the back seat.
Used in vehicles' ventilation system, the AC blower is responsible for circulating the conditioned air inside your vehicle. Without it, you can't expect your ride's air conditioning system to work efficiently. Why? Because the conditioned air doesn't flow with enough force, you won't be able to deflect it in the direction you want. Thus, you only get cool air near the AC vent. Heat in other parts of the cabin would register in the thermostat, which would tell your AC system to work harder and use up more power. So to ensure the longevity of your ride's blower motor, make sure to check it regularly.
Life's too short to spend it fixing your ride's damaged AC blower. But then it's also too short to spend even some of it sweating buckets at your ride's back seat. So find a replacement that's better than what you have. Find a high-quality blower motor coated with corrosion-resistant material for extra protection. And never settle with second-rate auto parts stores. Instead, buy from one that offers low prices, superb quality, and technical assistance.
Blower Motor Buyer's Guide
- A blower motor is an electric motor that powers the fan in the HVAC system in your vehicle. When voltage is applied to this motor, it turns the HVAC fan which blows air into the passenger cabin of the vehicle.
- The blower motor can be found under the dashboard inside the passenger cabin, but in some vehicles, it’s located in the engine compartment.
- If you feel little to no air coming in from the AC/heating system, or if you hear unusual noises from the blower motor, then it may be time to check and see if you need a blower motor replacement.
- Before buying a blower motor replacement, you have to consider its compatibility with your vehicle’s year, make, and model, and its energy efficiency. Also, it’s best not to insist on repairs if your blower motor needs an immediate replacement.
- Depending on your vehicle’s year, make, and model, the price of a replacement blower motor ranges from around $10 to $600.
If your vehicle’s heating and air conditioning unit suddenly stops working, it can be a major inconvenience. Until you find time to fix it, you can temporarily address the problem by rolling down the windows or by wearing warmer clothing. However, prolonged exposure to extreme temperatures can pose some serious health risks, especially to children and the elderly. To avoid these health risks, you’ll need to address your air conditioning problems right away.
Problems with your vehicle’s heating, ventilation, and air conditioning (HVAC) system can be caused by a variety of factors. One of the potential causes is your blower motor breaking down. What is a blower motor and how do you know when it’s time to replace it? This simple guide will take you through the process of getting a motor blower replacement for your vehicle.
What is a blower motor?
A blower motor is an electric motor that powers the fan in the HVAC system in your vehicle. The fan, in turn, is what moves cooled or heated air throughout the HVAC system. In most vehicles, a single blower motor moves both hot and cool air, but this depends on the climate control system of a vehicle.
The blower motor and the fan are usually found under the dashboard on the passenger side. However, some vehicles might be configured differently. In some passenger cars and trucks, the heater box and the blower motor are located in the engine compartment. In larger vehicles like SUVs and vans, there is usually more than one blower motor: one in the heater box and another in the rear part of the vehicle.
How does a blower motor work?
The blower motor assembly usually consists of a direct current (DC) motor, its housing, and the HVAC fan. When voltage is applied to the blower motor, it causes the fan to spin. The motor is bolted down to the heater box in its housing so the fan can move large volumes of air throughout the cabin and the HVAC system.
Depending on the vehicle, the blower motor assembly might also include a blower motor resistor. A blower motor resistor is what controls the speed of the blower motor in most vehicles with 4-5 fan speeds. The switch or the AC dial sends a signal to the blower motor resistor. The resistor then controls the amount of current going into the blower motor. The blower motor turns the fan at the required speed.
Meanwhile, vehicles with automatic climate control systems use an electronic blower motor control module to control blower motor speeds. Automatic climate control systems use sensors and other electronic components to regulate the internal temperature of the passenger cabin.
Symptoms of a failing blower motor
There are a few tell-tale signs that your AC blower motor needs to be replaced. Below are the most common symptoms of a failing blower motor to look out for:
Weak airflow and pressure from the vents
Weak airflow coming in from the vents is usually the first sign that there’s something wrong with your car blower motor. For most vehicles, this indicates that the blower motor is nearing the end of its life. Though, in some cases, it’s an indicator that it needs to be inspected and maintained immediately.
HVAC fan not working at all speeds
The HVAC blower motor and blower fan resistor make it possible for the fan to operate at different speeds. If the AC system can’t perform at different settings, you could be dealing with a faulty blower motor or resistor.
No air coming in from the vents
If there’s no air coming in from the vents at all, your blower motor could really be broken and needs to be replaced soon. However, it’s recommended that you check both the blower motor and the resistor/s before replacing any component. A busted resistor module is usually the culprit when the HVAC fan doesn’t work so be sure to inspect them first.
Sometimes, you’ll hear unusual squeaks and rattling noises from the blower motor. These can be heard when the blower motor is worn out or have bad bearings. However, in some cases, these noises can be caused by debris and leaves that get inside the HVAC system through the dash vents. These foreign objects can be cleared out when you remove the motor from the vehicle.
Choosing the right blower motor
There are several things you have to keep in mind before purchasing a new blower motor. The most important thing is to make sure you get a blower motor that’s compatible with your vehicle’s year, make, and model. The blower motor you purchase needs to be similar to your previous one. This is to avoid any incompatibility issues regarding fit and wiring. If you want to purchase one that’s different from your previous blower motor, it’s best if you research or consult a professional first.
Second, if your vehicle’s HVAC system allows it, consider getting an energy-efficient blower motor over a regular one. This kind of motor runs at different speeds, depending on the demands of the climate control system. This type of blower motor will definitely save you fuel and energy.
Third, don’t try and insist on repairs if a replacement is necessary. Keeping a damaged blower motor will decrease the performance of your HVAC system. This will also damage the surrounding components and even costlier repairs might be needed as a result. To make sure your blower motor is in top shape, always include your HVAC system whenever you do your regular vehicle checks.

Important Facts You Need to Know About Blower Motor
Wonder where the air blowing through your vehicle's air-conditioning (A/C) or heater vents comes from? Well, drawing air into the A/C evaporator or the heater core is the job of the A/C blower motor. This motor is mounted near a set of air control doors; these doors direct airflow either towards the evaporator or the heater core, according to your demands. Once you activate the A/C or heating system, the A/C blower motor immediately gets to work drawing air from outside the vehicle. A clear indication of a faulty A/C blower motor includes no airflow when the blower is turned on. Before this happens, there are usually minor indications such as a blower motor that operates only at some speeds and a noisy blower motor. When a replacement is needed, Auto Parts Deal can give you a topnotch A/C blower motor at the most affordable price.

Buying a Blower Motor: The Dos and Don'ts
When the sale season hits and paints the whole town red, you'll see big, wide smiles in people's faces. You'll see people running round and about, rummaging for clothes and gadgets in the stores. The same thing goes for stores that sell car parts-car owners will definitely make the most of it every time their favorite shops go on sale. However, this doesn't happen really often. So if you need to replace a car part, say, your car's blower motor-which is really an expensive component, read these tips to make sure you get your money's worth.
- Determine what type of fan works in your car. The two basic types are the centrifugal and axial fans. The centrifugal type of fan is the most common among cars; however, axial fans are more promising because of certain characteristics such as compactness, low price, and light weight. For replacement, you need to buy a motor that is similar to your original one. But if you prefer to use a fan type other than what your car originally had, it's best to consult an expert technician if the other fan type is compatible with your car model.
- Choose an energy-efficient blower motor-a variable-speed motor. This motor can run at different speeds depending on what is required. It can run fast at engine start-up and slowly decrease its speed once desired temperature is achieved. This blower motor can definitely help save a lot of fuel.
- Buy only from trusted distributors to make sure there's warranty. It is a must for expensive parts like this.
- Do not buy used blower motors. Buying second-hand parts is really difficult and dangerous because it's hard to get the product details from the previous owner, or worse, from a junk yard. Remember that specs such as size and type are vital. Unless you get these information, do not pay for them.
- Do not insist on repair if replacement is badly needed. A common mistake among many car owners is buying repair kits and trying to fix the problem themselves. The only time they buy a replacement part is when they fail to restore it. End result? They'll be paying twice or thrice.
- Do not hesitate to ask questions if you are not sure of which blower motor to buy. Ask a dealer or technician, or read your car manual to learn more about this part.
