The most probable one is when one of your signals work fine while the other one stops working. Another symptom could be faulty hazard lights as they are controlled by the turn signals. There is also another sign when your turn signals stop responding completely. There are other signs as well which are not that significant like the signs either blink too rapidly or blinks slowly.

Causes For Turn Signal Problems:
Well next time you blame someone for not using the indicators, there is a high chance their signals simply don’t work. The reasons mentioned below will help you troubleshoot the cause behind this.
1. Faulty Light Bulb:
If a turn signal is not working, you should check the light bulb. If the bulb has fused it cannot produce light. Check if your light bulb is the issue by using another perfectly running light bulb in its place. The fix for this is quite easy. Simply, replace it with a new one. This is the most common reason for broken turn signals.
2. Faulty Turn Signal Switch:
A signal switch is a device near the steering which tells the turn signals to blink. If the switch is faulty the bulb won’t light up. This will require more knowledge about wiring and requires a professional check. A loose wire could also be a cause behind faulty turn signals.
3. Oxidised Bulb Sockets:
Any component in your car can corrode over time. This is about proper maintenance and regular cleaning. Oxidation like rusting can minimise the contact between the turn switch and the turn signals. Excessive dirt can also build up over time causing the signals to not work.
4. Faulty Fuse:
A fuse is a safety device that breaks when too much energy or heat is passed through it. It melts off with too much energy flow. A broken fuse will break the connection between point A to point B. If this is the issue causing problems to your turn signal, you will have to replace the fuse with a new one.
5. Faulty Flasher Module:
If the turn signal is working inside the car is working and not on the outside, the flasher module could be broken. The flasher module provides power to the turn signals with the help of a strip of lead. If this piece of lead is damaged then the turn signals outside will not work properly.
How To Fix A Faulty Turn Signal?
Fixing a broken turn signal is very complex and finding the cause behind it can be very difficult. You should leave it to the care of professionals and you should not try fixing it without prior mechanical knowledge. However, if you feel you can fix it by yourself the video below might help you.

A turn signal which is not working will not affect the other parts of your car but it is very dangerous. It is also illegal to drive without proper turn signals.

Most people will be ignorant about fixing this issue but it very important to get this fixed as soon as possible.
A 2012 study by the Society of Automotive Engineers found that failure to use a turn signal accounts for more than 2 million accidents every year. Therefore, it is very important to get this fixed.
