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.

What are the signs of a failing blower motor 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.
Is it easy to replace a blower motor resistor?
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.
What happens when the blower motor resistor goes out?
Power to the blower motor is fed through the blower motor resistor, so if it fails or has any issues power can be cut off to the motor. A blower motor without power will not be able to produce any air pressure, and as a result the heating and air conditioning system will be left with no air coming from the vents.
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.
Does a blower motor resistor have a fuse?
A fuse is often located on the resistor board. The fuse only protects the low and medium blower speeds. High speed will still work if the resistor fuse is blown.
How long does it take to replace a blower motor resistor?
Probably up to 15 minutes if it’s located behind the glove box & the glovebox is easy to remove !
Will a blower motor work without the resistor?
There are instances where a bad resistor will prevent the current from reaching the blower motor altogether. 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.
Can a blower motor resistor be bypassed?
In the highest speed state, the blower resistor is bypassed completely and the fan is connected directly to the car’s battery, which allows maximum current through the motor.
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 test a blower motor resistor?
Is there a fuse for 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 new blower?
- Poor or Airflow from Air Vents. This will be the first and most obvious sign your blower motor has a problem.
- No Airflow At All From Vents.
- Skyrocketing Energy Bills.
- Strange Noises When You Turn on the Heat.
- Overheating Blower / Weird Smells.
Does blower motor affect AC?
The blower motor blows conditioned air through vents in the home. The air conditioner circulates the cool air through the home to the temperature on the thermostat. This is done by spinning the air and it moves through the vents and ducts in the home. As the HVAC system ages, so does the blower motor.
How do you test a blower motor?
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.
How long does it take to replace a blower motor?
Blower motor replacement typically takes two to three hours to complete, at a charge of $75 to $150 per hour. That brings the cost of labor to $150 to $450, depending on the difficulty of the repair and the cost of labor in your area.
How long does it take to change a blower motor in a car?
This is around a 4 hour job by an experienced Tech. At home, by a Novice with decent skills, about 5 hours plus!
How long do blower motors last?
Blower motors are designed to last just as long as your furnace itself, anywhere from 10 to 20 years. Just as with any HVAC system, the better maintained and serviced your equipment is by experienced HVAC technicians the longer it will last and the fewer repairs you’ll face.
Will a blown fuse cause my heater not to work?
Yes modern cars have switch that controls the water flow to the vents inside the car. Blown fuse will prevent it from opening and will cause a car heater not to work.
How do I know if my heater fuse is blown?
You can quickly determine by checking resistance with a multimeter. A good fuse will have nearly zero ohms of resistance, if the fuse is blown there will be no reading.
How do I test a blower fan 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.
Why does the fan in my car only work on high?
The blower motor resistor is prone to shorts, corrosion, and overheating. When the resistor fails, typically, the highest setting is the only option that still functions. This is because the air from the blower motor is bypassing the resistor, thus gaining the maximum amount of voltage, resulting in full power.
How much does it cost to replace a blower motor on a vehicle?
“A new car blower motor costs about $50 to $100 for the part and $80 to $100 in labor. Add it up and you’re looking at a total charge of $130 to $200 for a new car blower motor.
Can you drive a car with a broken 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.
Why is my car heater making a clicking noise?
Heater. If you’re hearing a heater clicking noise in the car or clicking noise coming from deep within your dash, the problem is likely the blend door actuator. The actuators are either not positioned correctly, the gear may be stripped, or the actuator may be broken.
