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.
How do I know if my blower motor resistor is bad?
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 is a blower motor resistor?
A blower motor resistor costs anywhere between $1 and $400. Factors that can affect its price include its condition, configuration, material, and set or kit inclusions. Labor may cost you an extra $45 to $55, depending on your area.
Is a blower motor expensive to fix?
Replacing a blower motor costs $450 on average with a typical range of $250 to $800. With a warranty, you might pay as little as $150 for labor alone. For high-end models, like those with large motors or access issues, you might pay as much as $2,000.
Can you drive without a blower motor resistor?
except blower motor resistors don’t “wear out”; they stop working altogether, suddenly, when the resistance wire inside burns through. Even then, it’s safe to drive the car provided that it has no exhaust leaks which might permit carbon monoxide or oxides of nitrogen to enter the passenger compartment.
What happens when blower motor resistor goes bad?
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.
What happens when blower resistor goes bad?
When the resistor goes out, you might not be able to get any air to come out of the 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.
Why does my blower motor resistor keeps melting?
Trent, one of the biggest reasons for blower motor resistors to have shorten life is actually because of faulty blower motor drawing too many amps, some times melting wires/plugs, heating up resistors shortening their life. Many Dodge forums tell of this problem.
How do you 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 does it take to replace a blower motor resistor?
takes about 45 minutes.
How much does a blower motor for a furnace cost?
How much does a furnace motor replacement cost? On average nationwide, a furnace blower motor replacement costs $400-$600, including parts and labor. A single-speed blower motor costs around $450 to replace while a variable-speed motor costs $600+.
How much does it cost to replace a blower motor in a car?
“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.
How long does a blower motor last in a car?
For the most part, the heater blower motor on your car is supposed to last as long as the actual vehicle does. Due to the harsh conditions that this blower motor has to operate in, it will usually end up having repair issues. There are a variety of problems that the blower motor may have that will render it useless.
What’s a blower motor resistor?
The blower motor resistor is responsible for controlling the blower motor speed. Each fan speed selection is connected to one or more of the resistors in the blower resistor assembly. The change in resistance controls the current through the blower motor, which in turn limits the speed that the blower motor spins at.
Can you drive a vehicle 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. Start car and see if blower motor works. If fuse blows again, check for loose circuits.
Why does my blower motor only work on high?
Most car manufacturers use a series of resistors to make the heater blower motor run at different speeds. And when one or more of these resistors burn out, you’re usually left with only one heater blower motor speed—high. The resistor module is easy and inexpensive to replace.
What are the symptoms of a bad blower motor relay?
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.
