Many vehicles have two fuses for the blower motor, one in the interior fuse block and the other under the hood.
You need to use a multimeter and check for continuity from end to end of each fuse. If you have continuity, it's good. If it's open/no continuity, it's bad.
Either it's not getting electrical power or, more likely, the motor itself has simply burned out. A blower motor in an older vehicle is likely to burn out over time, and may need replacement.
First see if a new fuse blows with the blower unplugged. If it does then there is a short between the fuse and the blower and the wire harness will need to be inspected to see where the short is. If the fuse does not blow with the motor unplugged the motor is shorted and needs to be replaced.
Overheating is one of the most frequent occurrences that can render the blower motor inoperative. If the motor has overheated, it may shut itself down to prevent damage. You should keep your HVAC clean and clear of any blockages or debris to avoid overheating and maintain efficiency.
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.
Blower motor is fuse 35 and is a 40 amp. You could test them with a meter or visually look to see if they're blown, then take it to a shop if they blow after replacing them.
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.
The blower motor resistor is responsible for controlling the blower motor speed. In the past, this was done by varying the voltage supplied to the blower motor. In newer applications, the blower motor resistor is actually a solid state module that sends a varied signal to the blower motor.
This could happen for a wide variety of reasons, such as a faulty wire, broken switch, or blown fuse. Another common reason is your compressor not turning on because it doesn't have enough refrigerant. Most compressors won't turn on if they go below a certain refrigerant level.
The most common reason why your blower motor won't work on any speed is that you have a bad or blown a fuse. A fuse is a small wire inside of a connector that is used to protect the motor itself from a surge of electricity.
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.
SMOKE OR SMELL WHEN DRIVING
In that case, immediately pull over. 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 replacement of the blower motor is common and straightforward, so most shops will perform the repair — many on the same day.
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.
First, turn off the power supply to the furnace by turning off the breaker in the circuit box. Locate the reset button on the furnace and press it to reset the furnace. It is usually located inside the blower compartment on the side of the blower motor. Be cautious, as the housing may be hot.
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.
It depends on the design of your specific car, but it's possible that your blower motor has a fuse. The blower motor is what powers the fan on your car heater.
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.
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.
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.
