Why is my car fan blower not working?
If your car's fan blower is not working, it could be due to a variety of issues, from a faulty blower motor to a problem with the electrical system. In this article, we'll explore the common causes of a non-functioning car fan blower and provide steps you can take to diagnose and fix the problem.
Common Causes of a Non-Working Car Fan Blower
There are several potential reasons why your car's fan blower may not be working:
- Faulty Blower Motor: The blower motor is responsible for powering the fan that circulates air through the vents. If the blower motor is malfunctioning, the fan will not turn on. This could be due to a problem with the motor itself or a wiring issue.
- Blown Fuse: The fan blower is typically powered by a fuse in the car's electrical system. If this fuse has blown, the fan will not receive power and will not work.
- Faulty Blower Motor Resistor: The blower motor resistor regulates the speed of the fan. If this component is faulty, it can prevent the fan from working properly.
- Wiring or Electrical Issues: Problems with the wiring or electrical connections in the fan blower system can also cause the fan to stop working.
Determining the exact cause of the issue will require further diagnosis and troubleshooting.
Diagnosing a Non-Working Car Fan Blower
To diagnose the problem with your car's fan blower, you can follow these steps:
- Check the Fuse: Locate the fuse for the fan blower in your car's fuse box and inspect it for any signs of damage or burnout. If the fuse is blown, replace it with a new one of the same amperage rating.
- Test the Blower Motor: Disconnect the blower motor and use a multimeter to check if it is receiving power and functioning correctly. If the motor is faulty, it will need to be replaced.
- Inspect the Blower Motor Resistor: The blower motor resistor is often located near the blower motor. Use a multimeter to test the resistor and ensure it is working properly.
- Check the Wiring and Connections: Inspect the wiring and electrical connections in the fan blower system for any signs of damage, corrosion, or loose connections. Repair or replace any faulty wiring as needed.
If you're not comfortable performing these diagnostic steps yourself, it's best to have a professional mechanic inspect and repair the issue.
Fixing a Non-Working Car Fan Blower
Once you've identified the root cause of the problem, you can proceed with the necessary repairs:
- Replace the Blower Motor: If the blower motor is faulty, you'll need to replace it with a new one.
- Replace the Blower Motor Resistor: If the resistor is malfunctioning, you'll need to replace it.
- Repair or Replace Wiring: If the issue is with the wiring or electrical connections, you'll need to repair or replace the affected components.
After making the necessary repairs, test the fan blower to ensure it's working correctly. If the problem persists, you may need to seek further assistance from a professional mechanic.
Can I replace a blower motor myself?
Undo the screws on the motor to remove the belly band. The rotation of the motor needs to match the direction of the fans, so position them accordingly. Attach the new motor to the belly band. Center the new motor on the fan wheel, fasten the bolts, and connect the capacitor.

Why is my car not blowing air from the vents?
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.
What can cause a car blower motor to stop working?
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.

6 Signs of a Bad AC Blower Motor
- Weak Airflow From Your Vents. One of the first signs you may notice is what feels like less air coming from your vents.

What would make a blower motor not work?
When you have NO speeds, it's probably the motor, but could be the blower speed switch or fuse. Check the fuse and test for voltage at the motor, and replace the motor if it's getting power but won't spin.
