Where is the AC blower motor fuse located?
The AC blower motor fuse is typically located in the vehicle's fuse box, which is usually found in the engine compartment or under the dashboard. The exact location can vary depending on the make and model of the vehicle, but the fuse box is the first place to check when troubleshooting issues with the AC blower motor.
Understanding the AC Blower Motor Fuse
The AC blower motor is responsible for circulating the air through the vehicle's air conditioning system. It is an essential component that ensures the proper functioning of the AC system. The blower motor fuse is a protective device that prevents the blower motor from drawing too much current, which could potentially cause a fire or other electrical issues.
The fuse is designed to "blow" or disconnect the circuit when the current exceeds the fuse's rated capacity, effectively shutting off the blower motor to prevent further damage. Locating and replacing a blown fuse is a common troubleshooting step when the AC blower motor is not working properly.
Finding the AC Blower Motor Fuse
To locate the AC blower motor fuse, follow these steps:
- Identify the fuse box in your vehicle. This is typically located in the engine compartment or under the dashboard, depending on the make and model.
- Consult your vehicle's owner's manual or the fuse box diagram, which is often located on the underside of the fuse box cover, to determine the location of the AC blower motor fuse.
- Once you've identified the fuse, visually inspect it to see if it has blown. A blown fuse will have a broken or discolored metal strip inside the fuse casing.
- If the fuse is blown, replace it with a new fuse of the same amperage rating. Do not use a fuse with a higher rating, as this could lead to further electrical issues.
After replacing the fuse, start the vehicle and test the AC blower motor to ensure it is working properly. If the fuse blows again, there may be an underlying issue with the AC system that requires further diagnosis and repair.
How to reset blower motor fuse?
How to Reset the HVAC Blower Sleeper Fuse
- Locate Fuse Box. You should first start by finding the fuse box which powers your HVAC system.

- Inspect for Damage.
- Replace the Fuse.
- Close the Panel and Test for System Function.
- Call an Expert if the Fuse Reset Doesn't Work.
Is there a fuse for the AC blower motor?
YES, the blower motor is related to the "AC" fuse. But keep in mind, there may be a "maxi fuse" that powers up the "AC" fuse.
How can you tell if a blower fuse is blown?
- Use a Multimeter: Set a multimeter to the continuity setting. Touch the probes to the ends of the fuse. If the multimeter beeps or shows continuity (a reading close to zero), the fuse is good. If there's no continuity, the fuse is blown.
Where is the blower motor reset button?
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.
How many fuses does a blower motor have?
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.
What to do if your blower motor is not working?
If your heater blower motor not working or heater fan motor not working, check for signs of wear and tear on the motor, belts, or bearings. Mechanical failures often result from years of operation without proper maintenance. A motor replacement or repair may be necessary to restore function.
What is the most common cause of a blown motor fuse?
1. Overloaded Circuit. The most common cause of a blown fuse we see as experienced Electricians in Sheffield is when something draws too much power from the circuit. This is most often caused by either too many lights or from using too many plug-in appliances at once.
Where is the reset button on the HVAC system?
In AC systems, the air conditioner reset button is on the outside unit's lower edge, typically close to the ground. Some models have the reset button located behind the service panel, which may require tools to remove. Reset buttons are usually red or yellow with a clear “reset” label.
Can a bad AC fuse cause AC not to work?
Without the fuse, your air conditioner could be damaged by the current and you could end up needing to replace the whole unit. Because the fuse has blown, the air conditioner is protected. If your AC fuse is blown, it's most likely that your air conditioner will stop functioning entirely.
Can a blown fuse cause a blower motor not to work?
Yes, a blown fuse can cause a car heater not to work. The car's heating system relies on various electrical components, including the blower motor, which circulates air through the heater core.
