How long does a blower motor for car or truck HVAC systems last? A. The blower is supposed to last the entire lifetime of your car.
Weak Airflow or No Airflow at All
Weak airflow or no airflow from the vents is a common sign of a worn-out blower motor. Blower motors are subject to wear and tear like any other car part, which could hamper the flow of air coming from the HVAC system.
One of the most telling signs is if the blower motor isn't blowing air at all or the airflow is weaker than usual. If you set your AC or heater to the highest setting and barely feel a breeze, your blower motor control module could be the issue. Another symptom to watch for is the blower motor running inconsistently.
The average cost for a Blower Motor Replacement is between $342 and $362. Labor costs are estimated between $68 and $86 while parts are priced between $274 and $276. This range does not include taxes and fees, and does not factor in your unique location.
We are going to list them out here and if you want to jump to a specific section you can, but the main reasons a blower motor will stop working at any speed is: A Bad Fuse. A Bad Ground Connection. A Bad Speed Control Module.
Your AC's blower motor is responsible for moving air through your air conditioner to cool it and then pushing it back out into your home. Without this incredible component, your AC can't provide any cooling effect, no matter how much the compressor runs.
The blower is supposed to last the entire lifetime of your car. However, situations vary and some climates require the fan to be used too often. Many car owners find themselves having to replace the blower after five years. The quality of the motor used to power the blower matters.
SMOKE OR SMELL WHEN DRIVING
A burned blower motor cannot exactly damage your car but you are not sure that the smoke is coming from the blower motor. Such signs indicate damage and you must tow it to a mechanic before turning the engine back on.
You can reasonably expect to find replacement blower motors at Parts Geek from $20 to $120, while the majority of these motors cost between $190 - $275 when you buy them from other parts stores. Costs for this part depend on several factors: Compactness of design. Levels of blower precision.
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.
Blower motor repair is only one of the options when your car AC system shows signs of failure. And while fixing problems will keep the motor going for a little longer, it isn't possible if it's too worn or burnt out. If you cannot fix it, replace it.
Blower Motor Resistor Test
Typically, if the fan will work on some speeds but not on others, the resistor is suspect. Okay, let's say there's no melting going on, but your fan doesn't work on all speeds. Typically, if the fan will work on some speeds but not on others, the resistor is suspect.
Without the motion of the fans, the air will not be moved properly, and thus the until will not cool your home. The best way to keep your AC fan motor running properly is to ensure it gets regular maintenance and air conditioning repairs by a professional.
Car AC Not Blowing Cold Air: A Bad Fuse
Find the fuse associated with the A/C blower motor. If the blower motor fuse is still in-tact, your problem is located elsewhere. If the fuse is blown, simply replacing the fuse with an identical fuse of the same amperage rating could get your system working again!
Repairing a blower motor costs anywhere from $150 to $1,500, depending on what went wrong. On the other hand, a full replacement might cost upwards of $2,000 once you factor in labor costs. So if your repair estimate is sky-high, you might get a better value with total replacement.
Typically, the lifespan of furnace blower motors spans from a minimum of 10 years up to about 20 years, with most enduring an average period between 15 and 20 years. The same blower motor is used for both heating in the winter and cooling in the summer, making it essential for maintaining indoor climate control.
Your car's HVAC 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.
In conclusion, the blower motor is a crucial component of your vehicle's HVAC system, responsible for circulating air throughout the cabin. Replacing a blower motor regulator or resistor can cost between $280 and $560, depending on the make and model of your car and labor costs, which can take one to three hours.
The blower motor relay fails because it regularly deals with high current loads. As a result, it can overheat and eventually melt, resulting in the relay fusing itself into the fuse box.
Blowers. From this table, blowers have an average effective life of 15-20 years.
If the motor is making rattling, clanking, or banging sounds, it may be because of a loose or broken part inside the system. Loud banging sounds are especially worrisome. They're usually a sign that something within the system is damaged or disconnected, potentially indicating the need to replace the blower motor.
In most newer systems, the button is often directly next to the blower motor, while in older systems, it may be harder to spot as it is sometimes underneath or behind the motor. The reset button is often made of yellow or red plastic and marked with a large “R ” to make it easier to spot.
If the motor either burns out or short circuits, it will not function at all, which means you won't get any hot or cold air. In most cases, the mechanic servicing your vehicle will need to replace the blower motor entirely if you are to have restored operation in the system.
