Why Car Indicators Not Working?

Indicators are the crucial parts of any vehicle. Just as we need some inspiration or guidance for our life path, similarly, the indicators are meant for providing a direction to the vehicle’s route and responsible for a smooth and safe journey.

We are here to give you your desired guidance for your vehicle. The car indicators not working can result in severe issues and problems; thus, they need correction within a limited time. Driving with non-working indicators can be life-threatening so, to avoid this and help you know the cause and its fixation, our article guides you step by step to reach your destination. So, let’s begin with it.

Why Are Indicators Important?

Indicators or turn signals are critical and vital for your car’s safety. They help in smooth and safe driving. Indicators allow the other drivers to know where our car will stick our way and thus prevent various accidents.

A car with faulty indicators is not safe to drive as well as it is illegal to drive the vehicle if the indicators are not working. Hence, it is crucial to fix the non-working indicators.Indicators are primarily amber in colour. They are located at the front, the rear and sometimes at the side of the car. We generally use an indicator to show the intended change in the direction of our vehicle. There are usually three types of indicator- position indicators, reason indicators, and objective indicators.

Reasons Why Car Indicators Stopped Working?

There are a wide variety of reasons for the malfunctioning of indicators, but the most common reasons are listed below:

1. Blown Fuse

Fuses are responsible for providing overcurrent protection to our vehicle. They are usually low current resistors that limit the excessive current flowing in the circuit. Hence, the electrical devices do not damage.

So, in short, it decides how much current can transfer to different parts of your car. The indicator light relies on a fuse to work, and thus if the fuse blows, it won’t work until replaced.

2. Malfunctioning Indicator Switch

The switch’s function is to send a signal to the indicators to turn them on and off when needed. If the switch breaks or malfunctions, there would no sign which communicate between the turn signal lever and turn signal light.

Thus, the signals would not circulate, and the indicators won’t work.

3. Bulb In Need Of Replacement

All the lights and bulbs have a limited life span; thus, in regular time-interval, they need replacement. The most common reasons for the blow of bulbs are – excess vibrations or faulty regulators, blown due to old age, and overcharging of the car battery.

Generally, turn signal lights may last for many years before burning out, but sometimes they die earlier than expected with the high frequency of use.

4. Dirty Bulb Sockets

It is also one of the reasons why indicators not work. The connection between the socket and the bulb can be interrupted by the dirt and debris present in the bulb’s socket.

Therefore, we need to clear it out to avoid such issues and problems. The oxidization also sometimes initiates this kind of problem.

5. Interrupted Circuit

The electrical circuit provides power to all the indicator lights. Thus, the damage or broken wire in the indicator circuit can interrupt the current flowing between the indicators and hazardous light bulbs, also limit or completely stop the bulb from working.

Hence, they need replacement as well as repair as quickly as possible.

How To Fix The Car Indicators Not Working?

As we know, indicators are an essential part of our vehicles, so whenever they face any malfunctions, they need to treated to avoid any further issues. Thus, the fixation of indicators need to perform in the following steps:

Step 1:

First of all, test the electrical system of the vehicle. For this, you need to turn the ignition key “ON” but make sure that you do not start the engine. Then, we will check all the indicators light.

Step 2:

In the next step, try to locate the fuse panel or the panel distribution centre (PDC) to check and test all the system fuses. The test of all the fuses is mandatory to know the cause of the problem. And also learn from where the problem has initiated.

Thus, you need to pay attention while locating the position as the exact location of the fuse is mandatory.

Step 3:

When a turn signal flasher or replay fails, the blinker will not operate. Thus, it will not switch on or blink. The primary purpose or function of the direction signal system is to work with a flasher or a blinker unit.

With this operation, the signals are generated, which causes the blinking action.

Step 4:

When the indicators or the turn signal switch false, the system will face a short circuit thus, leading the blinker not to operate. After this, you will use the test lights to check the system’s input and output power circuits.

It would help you know the origin of the problem, and hence soon you’ll solve the issue.

Step 5:

If the module of the system has any issue or problem, then a variety of lights would not operate. Thus, they need to update or reprogrammed as the lightning module used for controlling purpose.

How Much Does It Cost To Fix Turn Signals?

The average cost of fixing the indicators or turn signals ranges between $230 to $250, excluding labour charges. The labour costs are estimated between $80 and $100, while the parts are approximately $150.

These ranges do not include taxes and may vary from place to place, and it also depends on the extent of harm to your vehicle.


With the regularly scheduled service and the proper maintenance of your vehicle, you would not face the conditions where the car indicators not working. And if you ever found yourself stuck in such a situation, then follow the above-mentioned steps sequentially.
