Is it hard to replace a blower motor?
The replacement of the blower motor is common and straightforward, so most shops will perform the repair — many on the same day.
How much does it cost to fix a blower motor in car?
What happens when blower motor resistor goes bad?
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.
How can you tell if a blower motor resistor is bad?
A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. The blower motor resistor is the component directly responsible for controlling the blower motor fan speed. If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed.
What causes blower motor resistor failure?
In most cases, a blower motor resistor fails due to corrosion or overheating. Sometimes, the mechanical resistance to the motor rotation causes an excessive electric current that can overheat and prematurely damage the blower motor resistor.
Will a blower motor work without the resistor?
Without any power, the motor won't run. As a result, the blower fan stays still and silent, and no air blows out of the vents. There are instances where a bad resistor will prevent the current from reaching the blower motor altogether.
Should I replace the blower motor and resistor at same time?
We do suggest that you replace the resistor at the same time. It may not be critical, but this will keep the system more uniform. The issue may even be related to the resistor. If you know that it is not related to the issue, then you do not have to replace it.
How do I test a blower motor resistor?
Place one lead of the Ohmmeter on terminal 1 of the resistor. Place the other lead on terminal 2 and check against specifications. If this circuit is open, showing infinity on the Ohmmeter, the blower resistor must be replaced. Move the lead from terminal 2 to terminal 3 and check this reading against specifications.
How long it takes to replace a motor?
Engine Replacement Labor Cost On a typical engine, the shop time quoted will be 10 to 12 hours. On an easy engine with a skilled mechanic, you may get quoted as little as 8 hours, while bigger jobs may require as many as 15 hours. The majority of quotes should fall in the first time frame.
When should I replace my blower motor?
If the motor is making rattling, clanking, or banging sounds, it may be because of a loose or broken part. Loud banging sounds are especially worrisome. They're usually a sign that something is damaged or disconnected. And this may mean replacing the blower motor.
What does a blower motor do in a car?
The blower motor is the fan that pushes heated or cooled air through dashboard vents based on the climate system settings and the fan speed selected. Adjusting the fan speed sends a signal through a resistor to the blower motor to either pick up the pace or slow it down.
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 long should a blower resistor last?
How long should a blower motor resistor last? While a blower motor resistor is built to last for the car's lifespan, you can expect it to last for 10-15 years, but it's possible for them to last longer or shorter depending on the climate, driving habits, and quality of the resistor.
Do I need to disconnect battery to change blower motor?
Here is how to replace a car's blower motor: Clear a space: You need room to work and safer conditions. Start by disconnecting the negative battery terminal so you do not have a shocking experience.
Where is the blower fan resistor located?
The blower motor resistor is usually extremely easy to access, but the hard part can be positioning your body inside the car to remove the part. The resistor is at the bottom of the HVAC housing or just behind the glove compartment.
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.
Can you drive a car without a blower motor?
Your car's blower motor is not only necessary for the operation of your air conditioner. Without a functioning blower motor your engine runs the risk of overheating.
How can I tell if my blower motor is bad in my car?
You might also hear ongoing whirring noises, or noises that change or get louder if you increase the fan speed. These are all signs of problems with the blower motor. In some cases, you may even notice smoke or smells of burning while driving, in which case you should pull over immediately.
Why is my car making a weird noise when I turn the heat on?
Loud noises you hear when your car's heater or air conditioner are on typically indicate a blower motor issue. The good news is that a blower motor problem like this can be the result of something as simple to fix as debris or trash that got caught in it.
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 much does it cost to replace blower motor resistor?
In general, you can expect to pay between $50 and $200 for the labor associated with blower motor resistor replacement, giving you a grand total of between $60 and $260 for parts and labor. How long should a blower motor resistor last?
What happens when a blower motor resistor goes bad?
Blower motor resistor problems. 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. In most cases, a blower motor resistor fails due to corrosion or overheating.
Where is the blower motor resistor on a car?
The heater blower motor resistor is often found beneath the dashboard. It is located in the heater and air conditioning compartment. It’s connected to the air conditioning system, where it can adjust the speed of the blower motor fan. It can also be found behind the glove box of some vehicles. Either way, you will find it close to the blower motor.
How to test a blower motor resistor fuse?
Test the blower motor resistor fuse Once the blower motor resistor fuse is located, the next step is to test if it's working properly. To do so, use a 12 Volt test light and connect it from one side to the ground and the other side to the fuse terminal. Monitor the behavior of the power on the terminals and see if the fuse is working properly.
