When you need heat in a hurry in your car's cabin, the blower motor will have to spring into action.
What happens when car blower motor goes out?
If the blower motor is completely bad, then you'll have no airflow at all. Strange sounds coming from blower. Blower motors can make all kinds of sounds, depending on what the issue is. Vibrations, grinding, and high pitched-noises are some of the sounds a blower can make if it's going bad.

How much does it cost to replace a blower motor in a car?
How do I know if I need a blower motor or a resistor?
Signs of a Bad Blower Motor Resistor Loss of HVAC fan control (total or certain speeds) The fan only works on its highest speed setting. No air coming from vents. Intermittent or inconsistent fan speed.
Can a bad blower motor cause no heat?
Problems with Your Blower Motor or Blower Motor Resistor Without it, there's no circulation of air—hot, cold, or otherwise. The blower motor resistor is the part that controls the fan speed of the blower motor. Both of these components can fail, resulting in the heating system simply not working.
How long does it take to replace a blower motor in a car?
How Long Does It Take To Replace A Blower Motor In A Car? It generally takes about 4 hours for an experienced technician to do a blower motor replacement. If you are doing it on your own in your garage with common tools, you can expect the job to take 6 hours or more.
Does the blower motor control heat?
The blower motor is an important part of your vehicle's heat and air conditioning systems. Without it, you can't control the temperature of your cabin — not a dire consequence, but definitely a major annoyance in extreme heat or cold.
What does the blower motor do?
The blower motor turns the blower fan, sending the air through your air ducts and into each room of the home. If your blower motor is single-speed, it will operate at 100% speed until the thermostat indicates that the desired temperature has been reached.
Can a bad blower motor cause overheating?
As you may know, the heater not working in some cases may be related to the overheating problem you are also having. This may be due to a faulty heater blower motor or potentially a bad heater core.
How many blower motors are in a car?
The number of blower motors in your vehicle depends on its climate control system. Some cars have one blower motor, but that may not be the case for some SUVs and vans. They may have two motors, one in the heater box and another in the vehicle's rear area.
How often do blower motors go out?
How long does it take to replace a blower motor in a car?
How Long Does It Take To Replace A Blower Motor In A Car? It generally takes about 4 hours for an experienced technician to do a blower motor replacement. If you are doing it on your own in your garage with common tools, you can expect the job to take 6 hours or more.
What happens when your blower motor resistor goes out?
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's a blower motor resistor?
Blower resistors are resistors which are used to control the fan speed of automotive blowers. The fan speed can be changed either by switching the blower resistor resistance mechanically using a rotating lever, or electronically by the air conditioning system.
Are blower motors expensive?
Cost to Replace Central or Forced Air Blower Motor Replacing a blower motor costs $450 on average with a typical range of $250 to $800. With a warranty, you might pay as little as $150 for labor alone. For high-end models, like those with large motors or access issues, you might pay as much as $2,000.
Why is the blower motor making noise?
Furnace blower motor noise when starting is likely due to damaged or worn-out parts. Humming, screeching, or thumping sounds are usually signs of underlying problems. Identifying and correcting the issue can get rid of the sound and also ensure the longevity of the wider furnace system.

What is the difference between a fan motor and a blower motor?
What Is a Blower Motor? Unlike the condenser fan motor, the blower motor is located indoors. It's the component that blows cool air through the ducts and into different parts of your home. So it's essentially your air mover.
Is there a fuse for the blower motor?
How much does it cost to replace a blower motor resistor?
How much does a blower motor resistor cost? To replace the blower motor resistor, it would cost you anywhere between $50 to$150 – this includes the cost of equipment and labor. However, by doing it yourself at home, you can save up to $70.
How do you test a blower motor on a car?
Turn off your vehicle, set your multimeter to Ohms, and check for resistance between the blower's positive and negative terminals. You may also turn the car key to run without starting the engine, put the cooling system at full blast, and check for DC voltage. If none of these produces a reading, the blower is bad.
What does a bad blower motor sound like?
A defective blower motor will make a continuous sound noticeable by the passengers in the vehicle. It can manifest as a knocking, whirring, clunking, vibrating, squealing, or whining noise that persists until the blower motor is replaced.
Can you drive a car with a burned out blower motor?
A blower motor that’s burned out won’t wreck your car, but you also cannot be sure right away that it’s the blower motor that’s smoking. You should get your vehicle checked out before you continue to drive at all if you notice these issues.
Why is my car’s blower motor not blowing cold air?
Your motor will wear out over time—this is just part of the general wear and tear your vehicle experiences. As this happens, it means the motor won’t be able to push as much air through your vehicle’s HVAC system, so you’ll start to notice that the blowers aren’t nearly as powerful as they once were.
