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.
Where is the blower fan motor located?
How much does it cost to replace a blower motor on a BMW?
BMW 328i Blower Motor Replacement Cost Estimate. The average cost for a BMW 328i blower motor replacement is between $450 and $492. Labor costs are estimated between $117 and $147 while parts are priced between $333 and $345.
Where is the location of the blower motor resistor?
Locate the blower motor resistor. It can be found below the blower motor. In some vehicle’s you need to remove the glove compartment to access the blower motor resistor. Now that you’ve located the blower motor resistor, you’ll now need to disconnect the resistor from the housing and then remove the harness.
What is a blower motor on a BMW?
The blower final stage fan resistor also goes by the name of the blower motor resistor. This component is an electrical part responsible for providing the voltage to the fan that controls the heating and air conditioning in your BMW. You can find a blower motor resistor in BMWs that have 4 or 5 fixed speeds.
Is a blower motor easy to replace?
The replacement of the blower motor is common and straightforward, so most shops will perform the repair — many on the same day.
How do I know if my blower motor is bad?
Weak or Absent Airflow Weak airflow or total lack of it is the most obvious sign of a bad blower motor. The problem could be due to a clogged blower from accumulated dust or debris. It could also be due to leaky air ducts or a bad capacitor.
Can you drive 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 BMW not blowing air?
One of the most common reasons your BMW’s air conditioner isn’t working is because of an A/C leak. The fluid that is used to cool your car, freon, could be leaking out of your car, or there might be a bigger leak in the A/C system.
Should I replace both blower motor and resistor?
The heater blower motor resistor can often go bad because of a bad heater fan, and therefore you often have to replace both the heater blower resistor and the fan.
Is there a fuse for blower resistor?
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.
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.
What happens when blower motor goes bad?
FAN BLOWS AT ONLY A CERTAIN SPEED A malfunctioning blower motor works at a particular speed only—however, a perfect blower motor functions at various speeds as per the car’s cabin temperature. Hence, if the blower motor fan does not blow the required amount of air, then it’s a sign of a bad blower motor.
What happens when a blower motor fails?
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.
What happens when a blower motor stops working?
Blower motor resistor / control module problems 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.
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 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 a blower motor usually last?
The blower motor in your home or office should last anywhere from 10 to 20 years. Modern sealed bearings and sealed bushings can push the lifespan to its maximum of 20 years. Proper cleaning and maintenance can also extend your unit’s lifespan.
How much does it cost to replace a car blower motor?
“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 often do blower motors go out?
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.
How much is labor for a blower motor?
Labor to install a blower motor costs around $150 to $410. Most of that cost comes from trip fees and labor. Furnace repairs cost at least $100 to $200 but usually include the first hour or two of work. An HVAC technician runs around $75 to $140 per hour, typically taking two to three hours to complete the job.
How do I know if it’s my blower motor or 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.
Can the blower motor stop AC from working?
Having a dirty blower wheel will make your HVAC system work harder and, if not addressed, eventually cause your AC system to stop working. A dirty blower wheel will also contribute to a high electric bill. Damage caused by a dirty blower can be costly to fix– but can be prevented too!
What causes a blower motor to fail in a car?
A defective ground wire or ground wire connection and an open circuit in the power-side circuit (including the fuse, wiring, and fan switch) are the most common reasons why a blower motor fails. Blower motors can also just fail from regular use due to time and mileage.
Why is there no air blowing out of my vents 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.
