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.
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.
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.
Is there a fuse for the blower motor?
If the fan doesn’t work, before pointing the finger at the blower motor, check fuses for the motor to make sure they’re still good. 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 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 in a car?
A new blower motor will run between $50 and $100. Most blower motors sit in the dash underneath the glove box, and are accessible for replacement. Installation will run in the range of $80–$100.
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 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.
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].
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 a blower motor get weak?
A worn or weakened blower motor may not be able to provide adequate airflow to properly regulate the cabin temperature, and may also be approaching the end of its service life.
Why did my air stop blowing in my car?
Here are some of the most common causes of why air doesn’t flow out of your vehicle’s vents: Your air intake is clogged, meaning that air isn’t getting in from the outside at all or isn’t circulating properly. There is a blown fuse in the ventilation system. Electrical issues such as a bad relay.
