If your turn signal suddenly stops working and hazards continue to work, this could indicate a mechanical issue, such as a bad connection or dirty contacts. To determine the cause of your turn signal issues, you should have tests performed by a professional. This article will look at the reasons your turn signal may not work.


Why Are Turn Signals Important?

Turn signals are essential for a couple of reasons. First, they allow you to communicate with other drivers and pedestrians that you are about to turn.

Also, when you are stopped at an intersection or stop sign with traffic approaching from either side, a flashing turn signal will tell them that it is safe to proceed past you without worrying about being rear-ended.


Solutions To Common Problems

Before you go ahead and check solutions to common problems, check out his video that can help you troubleshoot your turn signal problems.


Turn Signal Not Working

The first thing you should do if your turn signal isn’t working is to check the bulb. If it’s burned out, you’ll need to replace it. If the bulb is fine and there’s still no turn signal, you should check the wiring from the fuse block back to the steering wheel controls. You may need to replace some of this wiring if it’s damaged or corroded.

Hazard Lights Not Working

A flasher unit controls the operation of a hazard light. If the flasher is not working, it may not be able to activate the hazard lights when needed. If this happens, you should check for loose connections between switches and the hazard light switch, along with signs of corrosion around the connections.

Faulty Turn Signal Switch

If you are having trouble with your turn signal, it is likely that there is a bad connection with the turn signal switch. To test this, use a multimeter to check for continuity between the post on the switch and the white wire coming from the battery. If there is no continuity, replace the switch.

A Blown Fuse or Defunct Flasher

It would help if you also looked at the fuse or flasher in your car. If either of these is blown, it may be because of an electrical system issue. If this is the case, you’ll need to get a professional to come out and fix what’s wrong with your car’s electrical system.

Faulty Turn Signal Switch Connector

If you have a faulty turn signal switch connector, your turn signals may not work. There are two ways that this can happen:

  1. The wires inside the connector may have been compromised. This is most likely to happen if someone has jostled or bumped the car while driving it or if you’ve had an accident.
  2. The wires inside the connector may have disconnected from their connectors at some point. If this happens, your turn signals may not work.

Turn Signal Lights Not Turning Off

One of the most common problems with turn signal lights is that they won’t turn off. When this happens, it can be a significant safety hazard. You may have a problem with your turn signal switch or a fuse.

When this happens, check all fuses under the hood of your vehicle. This will help determine if there is a problem with power getting through to the turn signal switch itself. You may need to replace these fuses if they don’t seem like they’re working correctly anymore.

It’s important to remember that these issues can occur over time due to wear and tear from driving.

Turn Signal Flashing Too Fast Or Too Slow

Your alternator is responsible for charging the battery while the car is in motion, and it also powers the accessories in your vehicles, such as lights and power windows. If the alternator isn’t working correctly, this can cause issues with all of these functions. If your turn signal flashes too quickly or too slowly, you may need to replace the alternator on your vehicle.

Dashboard Turn Indicator Not Flashing

If your dashboard turn indicator is not flashing, there could be a fault with the flasher unit. The flasher unit is located at the back of the dashboard and is responsible for flashing the turn signal lights when you turn. It can be damaged by water, moisture, or other substances that prevent it from functioning correctly.

Check for water in your vehicle’s dash area or under the hood. You can also check where you suspect a leak if you see any water on the underside of your dashboard. If no leaks exist, then chances are something else is causing this issue.



If the turn signal is not working or blinking, the problem is likely a bad flasher unit. It’s possible that the flasher unit could be turned on but not receiving connectivity through the socket. Check all connections to the flasher unit and replace it if necessary. We hope this article covered all points regarding your turn signal or flasher not working.
