What are the signs of a bad blower motor resistor?
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.
What happens when your blower motor resistor goes bad?
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.
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.
Is my blower motor or resistor bad?
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.
What causes a blower motor resistor to burn out?
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. Then they buy a aftermarket blower motor and again it keeps burning up.
What causes a blower motor resistor to go out?
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.
Can a blower motor be repaired?
Blower Motor Replacement: When Good Parts Go Bad. There are a number of things that can go wrong with your heating system, but if the air stops blowing altogether and the same is true on cold air settings, a blower motor replacement is likely in order. The good news is that it’s a fairly straight forward repair.
How much does it cost to replace 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.
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.
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.
Is there a way to 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. Move the lead from terminal 2 to terminal 3 and check this reading against specifications. If this circuit is open, showing infinity on the Ohmmeter, the blower resistor must be replaced.
How do I know if my blower motor fuse is bad?
How to Test a Blower Motor
- Use voltmeter or ohmmeter to check for a blown fuse. If you find one, replace it.
- Start car and see if blower motor works. If fuse blows again, check for loose circuits.
- If the circuits are in good repair but the blower motor keeps blowing fuses, replace the blower motor [source: You Fix Cars].
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.
