What causes blower motor relay 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.
How much does it cost to fix 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.
What relay is for the blower motor?
The blower motor relay is the electrical switch that is used to supply the power for the vehicle's blower motor. The blower motor is the component responsible for pushing air through the vents of your vehicle's heating and air conditioning systems.

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 I know if my blower motor 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.
How do I test a blower motor relay?
Connect a test light or multimeter to the ground (black lead). Turn the ignition key to the on position (engine off), and remove the relay. Using the probe, test all terminal sockets in the relay connector. Two of the four should have power.
Is there a fuse that controls the blower motor?
Many vehicles have two fuses for the blower motor, one in the interior fuse block and the other under the hood. The blower motor is usually under the dashboard on the passenger side.
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.
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 happens when the blower motor resistor goes out?
No Air Coming From Vents The blower motor resistor controls the power to the system's blower motor. When it fails, it can cut off all power to the motor. When the blower motor doesn't get power, air pressure can't be produced. You are left with a heater or air conditioner with nothing coming out of the vents.
How can I tell if a relay is bad?
You want to feel and listen for any clicks. If you feel and hear clicks, the relay works on one side – the side with the energizing circuit and coil. However, if there was no sound from the horn, the relay has a problem along the contact circuit.
Where is the blower motor relay fuse located?
Under the instrument panel, look under the glove box. On the right side of the fender wall you will find another fuse box. The blower motor fuse is easy to replace.
How do I know if my AC relay is bad?
Common signs include inconsistent cooling, not hearing a click from the compressor turning on, and no cold air.
How do you test a blower motor relay?
Connect a test light or multimeter to the ground (black lead). Turn the ignition key to the on position (engine off), and remove the relay. Using the probe, test all terminal sockets in the relay connector. Two of the four should have power.
What happens when 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.
Is there a fuse that controls the blower motor?
Many vehicles have two fuses for the blower motor, one in the interior fuse block and the other under the hood. The blower motor is usually under the dashboard on the passenger side.
How does a blower relay work?
In a blower motor, the relay supplies the power that allows the fans to circulate warmed air. Essentially an on/off switch, the blower motor relay's reactions start and end the heating process in HVAC systems by controlling the flow of current between the power source and the motor.
How much does it cost to fix 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.
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.
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 much does it cost to replace a blower motor?
Does a blower motor have a relay?
In a blower motor, the relay supplies the power that allows the fans to circulate warmed air. Essentially an on/off switch, the blower motor relay's reactions start and end the heating process in HVAC systems by controlling the flow of current between the power source and the motor.
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.
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.
What can cause a blower motor to stop working?
Blower motors are designed to circulate air, so they won't work if there's no air to move. You should always check the filters and vents surrounding the blower to make sure that the blower isn't having a hard time working. Look into your air filter's housing and check the markings on your filter.
What factors determine the blower motor replacement cost?
The blower motor replacement cost will vary with the model and brand of your car. Another factor that dictates the blower motor replacement cost is the extent of the damage. The process starts with diagnosing the blower motor. That way the mechanic can find out if any other components are damaged.
Does a failed blower motor need to be replaced?
A failed blower motor definitely requires a replacement. The blower motor replacement cost depends on many factors and price will vary depending on those factors. A car usually has multiple blower motors located in different places.
Why replace a blower motor relay?
Replacing a malfunctioning relay restores your system’s ability to keep your home, building, or vehicle comfortable. How Does a Blower Motor Work? In an HVAC system, the thermostat sets the conditions for engagement.
How much is a blower motor resistor (repairs) cost?
Here are a few examples of how much is a blower motor resistor (repairs) to compare the pricing of common vehicles using an average US shop rate of $80/hr: 1. A 2011 Toyota Corolla 1.8L without automatic temperature control has a blower motor that only operates on “high”.
