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. Compactness of design. Levels of blower precision.
Replacing the blower motor is likely the best decision if your furnace is under warranty or relatively new. It might be better to replace the furnace if it's old or has a lot of issues that require frequent repairs.
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. Related repairs may also be needed.
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.
The most common reason why your blower motor won't work on any speed is that you have a bad or blown a fuse.
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.
In general, it can take two to three hours to replace a typical blower motor. If a highly qualified technician has the part in stock, it can take as little as 1.5 hours.
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.
The replacement of the blower motor is common and straightforward, so most shops will perform the repair — many on the same day.
Step 1: Prepare the vehicle
Start by disconnecting the negative battery terminal, and set it aside someplace where it isn't touching metal. If applicable, remove the passenger-side floor mat. Typically there is a plastic cover underneath your glove box.
Beyond temperature control, the blower motor also facilitates air circulation and ventilation within the vehicle. It helps distribute fresh air from outside or recirculate air from within the cabin, preventing stale odors and ensuring a clean and pleasant interior environment.
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.
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.
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.
One of the most prevalent factors that can cause a blower motor to stop working is a blown fuse. A fuse prevents electrical circuits from an excessive flow of current that may run in them.
Just about every car has blower fans that circulate air from the heating and cooling system; many vehicles have two or more fans in the cabin. High-end vehicles have fans built into the seats for cushion ventilation and heat distribution.
More specifically, systems that include blower motors have a lifespan of roughly: Air-Source Heat Pumps: 10 to 12 years, with a maximum of 15 years or more. Furnaces: 10 to 20 years, depending on maintenance schedules. DX Air Conditioners: 15 to 20 years, depending on maintenance schedules and manufacturer quality.
If the blower motor is going bad, it will struggle to operate the fan. The result will be weak airflow coming from the vents inside your living spaces. This airflow issue can be one of the main symptoms that indicate the component needs to be replaced.
Cost for a single-stage blower motor could run between $300 and $900, while cost for a variable-speed blower could be between $600 and $1,500.
The blower motor is responsible for circulating the air through the AC system. If the blower motor is not working, the air will not be circulated properly, which will cause warm air to be blown into your car.
On some platforms, a faulty blower motor relay will cause the blower not to work at all, which means there will be no airflow from the A/C. On others, the blower won't work on “high blow” but all the other speeds will work. The blower motor relay fails because it regularly deals with high current loads.
