Here are some common signs that your vehicle's blower motor resistor is bad: Loss of HVAC fan control (total or certain speeds) The fan only works on its highest speed setting. No air coming from vents.
How do I know if I have blower motor or resistor?
Typically, if the fan will work on some speeds but not on others, the resistor is suspect. Okay, let's say there's no melting going on, but your fan doesn't work on all speeds. Typically, if the fan will work on some speeds but not on others, the resistor is suspect.
Is it the blower motor resistor or blower motor?
The blower motor resistor is an electrical component that is a part of the vehicle's heating and air conditioning system. It is responsible for controlling the blower motor's fan speed.
Should you replace blower motor and resistor at the 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 you know if your car blower motor is bad?
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.

Is it the blower motor resistor or blower motor?
The blower motor resistor is an electrical component that is a part of the vehicle's heating and air conditioning system. It is responsible for controlling the blower motor's fan speed.
What happens when the blower motor resistor goes out?
Problems with a blower motor resistor are common in many cars. The most common symptom of a failed blower motor resistor is when the heater fan only runs at the highest speed setting (4 or 5) and doesn't work at low speeds. In some cars, a failed blower motor resistor can cause a heater fan to stop working completely.
How much does it cost to replace 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.
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.
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.
Where is a blower motor located?
The blower motor is usually under the dashboard on the passenger side. Blower motors that make loud squeaks or rattling noises may be worn out and on the verge of packing it in, but sometimes those noises are caused by leaves or other debris that can be cleaned out after the motor is removed from the vehicle.
Where is the blower 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.

Is there a fuse for blower motor?
How much does it cost to replace a blower motor in a car?
How long does it take to change a blower motor resistor?
The average cost to replace the blower motor resistor at a repair shop is between $44 and $55 in parts and $70 in labor costs, for a total cost of around $114 to $125. On the other hand, you can easily fix the blower motor resistor at home in about an hour (even if you're a beginner) and for around $70.
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.
How long does a car blower motor last?
What happens when a blower motor goes out?
WEAK AIRFLOW OF THE BLOWER MOTOR The fans will work at certain speeds until they stop working altogether. Such a fault not only results in poor airflow but also decreases the efficiency of the defroster as it uses the same fan to blow air at the windshield.
Can you drive with a bad blower motor?
Should you drive with a bad heater blower motor? A bad heater blower motor will not affect the safety of your car, with the possible exception of you not being able to clear the windshield of snow, ice, or condensation if the defrosters don't work.
What makes a blower motor go bad?
Blower motor breakdown can be the result of anything from old age to failed bearings, high amp draw, electrical failure in the windings, dirt accumulation, and more. “The most common cause is dirt accumulation due to lack of maintenance,” said Tom Beaulieu, president of Bay Area Services Inc.
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 replace a blower motor?
How do I know if my blower motor resistor is bad?
Let’s begin with a look at the signs to look for. The most common symptom of a bad blower motor resistor is that you will only notice that your blower is working on the highest speed setting or that it won’t work at all. Here’s a more detailed list of the most common symptoms of a bad blower motor resistor:
Do I need a new blower resistor?
Some of my friends say I need a new blower resistor because that controls the air flow or something and others say blower motor. I believe if I am moving on "no circulation" and the air is coming through the vents, then the blower motor is fine. Or that its just my vents are open and the air is coming from somewhere else.
What does the blower motor resistor do on a car?
No air from the vehicle’s vents The blower motor resistor is an electrical component that is a part of the vehicle's heating and air conditioning system. It is responsible for controlling the blower motor’s fan speed.
How to troubleshoot a blower motor problem?
If those are OK than backprobe the blower motor connector and check for power on terminal 1. Check terminal 2 for a variable voltage, this should be 12v with the fan control knob on off and 5v or full ground on full. If that checks out replace the blower motor.
