For safety purposes, it is necessary to have a proper functioning low air warning buzzer. It ensures that the driver has full control of the vehicle at all times and when the buzzer goes off, the driver should immediately look to park the vehicle.

This buzzer can save you from a lot of potential accidents where you might lose control of your vehicle.

If you believe that the low air warning buzzer in your vehicle is not working properly, then here is what you should do to get the low air warning buzzer working again.

How to Fix Low Air Warning Buzzer Not Working?

  1. Check Voltage

Insufficient voltage is one of the reasons why your buzzer might be malfunctioning. To verify, you will need to access the buzzer through the dashboard. Now, it can be a bit difficult to locate the buzzer depending upon the model of your vehicle.

However, it should be around the middle of the dashboard near the RPM gauge. After locating the buzzer, you need to check the voltage across the terminals of the circuit.

Ideally, the voltage should be around 12 volts and you can use any voltage measuring tool to get a reading.

If the reading on your measuring tool is significantly less than 12 volts then you need to take a look at the wiring and the power source. The buzzer will not work until it gets the proper power supply from the source.

  1. Buzzer Replacement 

If the voltage across the circuit terminals is sufficient then it may be that the buzzer is defective. Depending upon the age of the buzzer, it can go bad after a few years.

So, if you have had the vehicle for a long time, or you bought it from another owner then you should probably replace the buzzer. It is not that expensive and you won’t have any difficulty installing the buzzer.

To verify the integrity of the buzzer you can remove it from the panel and try using it with a 12 volts battery pack.

If it doesn’t work even with the new battery pack then you will have to buy a new buzzer because this one is defective. You can’t do anything to fix a defective buzzer and it is probably better to get a new one.

  1. Visit A Workshop

There is also a possibility that the circuit is fried, due to which you’re having issues with the low air warning buzzer. We suggest that you visit a workshop and let a professional take care of this issue.

You won’t have to do any guesswork and the mechanic will tell you about what is causing the buzzer issue. So, instead of wasting money on buying a replacement, you should first get a mechanic to take a look at your vehicle.

However, if you don’t want to visit a workshop then you can always try your luck with installing a new buzzer. Hopefully, that will fix the buzzer issue for your vehicle. Just make sure to visit the workshop afterward to ensure that the buzzer is working properly.
