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.The most common symptom of a blower motor resistor is that when you start the heater fan, it only runs at the highest speed setting. A bad or failing blower motor resistor hampers the efficiency of the heating and air conditioning system. A working resistor can shift between speed settings according to the user’s preference.
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.
What happens when a blower motor resistor fails?
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.
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.

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.
Is there a fuse for blower motor?
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.
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.

How do I know if my heater resistor is bad?
If you try to increase the air pressure and you feel no difference in the pressure blowing, then your blower motor resistor may be failing. A damaged blower motor resistor will work on one fan speed which may not be enough to keep the inside of your car cool or warm enough.
How do I know if my blower relay is bad?
If you have a faulty blower motor, you may experience low airflow from the vents, even when the fan is on high. There will be no air coming from the vents if your fan isn't working due to a bad blower motor resistor. Blown relay circuit fuses or melted relays are more serious signs of a bad blower motor relay.
Why is my car blowing out cold air when the heat is on?
Low Coolant Level The coolant (usually a mixture of water and antifreeze) in your engine doesn't just work to keep the engine from overheating: It's also the source of heat supporting the heating system. If there isn't enough coolant in your system, the heater core will blow cold air into your car.
What happens if my blower motor relay is bad?
If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current from a bad relay will blow the fuse and cut power in order to protect the system.
How much does it cost to replace a blower motor?
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.
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.
Is there a fuse for the blower motor?
Where is the blower motor reset button?
Locate the reset button on the furnace and press it to reset the furnace. It is usually located inside the blower compartment on the side of the blower motor. Be cautious as the housing may be hot. If the button is popped up, press it down.
How hard is it to change 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.
What happens if you have a bad blower motor resistor?
If you have faulty blower motor resistor you may experience low airflow coming from the vents even when the fan is all the way on high. In some cases bad blower motor resistor may not even turn the blower motor fan as a result your fan will not work at all and there will be no air coming from the vents.
How do I know if my blower fan motor is bad?
Give the blower fan a spin with your hand to see if there is any scraping or wobbles. Bad bearings are another reason why a blower motor might be bad. The bearings are the part that allows the motor shaft to spin freely. If you have bad bearings, then your motor will resist turning.
How do you test a blower motor resistor?
Here are some tips on how to test your blower motor resistor: Start by looking for the blower fan resistor. A repair manual can tell you where its location is in your vehicle’s make and model. Inspect the resistor visually. Look for obvious signs of corrosion and burns from overheating.
Why is my blower motor not working in my car?
In this car, in the highest "4" fan speed setting, the resistor is bypassed and the blower motor is powered directly by the fan switch. That's why in some cars, the blower motor may still work in the "High" speed setting if the resistor is bad.
