How do I know if my blower motor resistor is bad?
What are the symptoms of a bad blower motor resistor?
- No Air.
- High speeds only.
- Low speed only.
- Fan won’t turn off.
- Blower motor works on some settings but not others.
- Smoking vents.
- Burning smell.
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.
How long does it take to replace a blower motor resistor?
takes about 45 minutes.
What does the blower motor resistor control?
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. A failed blower motor resistor can cause issues with the operation of the entire heating and air conditioning system.
How much does it cost to replace a blower motor resistor?
Blower Motor Resistor Replacement Cost – RepairPal Estimate. The average cost for blower motor resistor replacement is between $115 and $141. Labor costs are estimated between $47 and $59 while parts are priced between $68 and $82. This range does not include taxes and fees, and does not factor in your unique location.
What causes blower motor resistor 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.
What happens when the blower motor 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.
How long does it take to replace a blower motor in a car?
This is around a 4 hour job by an experienced Tech.
How much does it cost to replace a blower motor?
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 with a bad 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. But you won’t be comfortable inside your car, especially during the cold of winter and the heat of summer.
How do I replace a blower motor resistor?
- Remove the negative battery terminal.
- Locate the blower motor resistor on the passenger side under the dash board.
- Disconnect the electrical connector to the blower motor resistor.
- Remove the screws or bolts to the blower motor resistor and remove the resistor.
- Installation is the reverse of the removal.
What are the signs of a bad blower motor?
Signs That Your Car’s Blower Motor Is Going Bad
- Weak airflow. This is one of the first signs of a bad blower motor that people tend to notice.
- Noises. Have you noticed any unusual noises coming from your vehicle’s HVAC system?
- Smoke or smells. In some cases, you may even notice smoke or smells of burning while driving, in which case you should pull over immediately.
Why is my blower motor not working?
In a situation where the motor doesn’t work on any speed, the most likely causes are: a blown power supply fuse, a bad motor ground connection, bad motor speed control module or a failed motor. On all systems, a failed blower motor is least likely. Start by checking the blower fuse and HVAC controller fuse.
Can you test a blower motor resistor?
Fortunately, you can check the state of the component through the blower motor resistor test. With just a multimeter, you can find out if it’s time to get a replacement. If your car’s blower has only 4 or 5 different speed settings, it likely uses a simple electric resistor to control the fan’s speed.
