A car is a big investment and something that has to be cared for in order for it to function properly. Making sure that all of the vital systems of a car are functioning properly should be one of the main things that you are concerned with. One of the most used, yet commonly neglected parts of any car is the turn signal switch. Most of the turn signal switches on cars these days have controls for the wipers and allow you to turn on your high beam lights. When you have to signal when changing lanes, you will have to rely on the turn signal switch to do its job.

Like any other electrical component of your car, eventually the turn signal switch will become unusable due to the wear and tear that it undergoes over the years. Not being able to use your turn signal switch can lead to a number of different issues and can compromise the level of safety that your vehicle has. As the years go by, the wiring inside of the turn signal switch will begin to become worn and may begin to become loose. This will lead to connectivity issues and the inability to signal when trying to change lanes. This can lead to a very dangerous situation which means the turn signal switch will need to be replaced by a certified mechanic.

If you start to experience issues with your turn signal switch, you will need to do a bit of troubleshooting in order to narrow down the issues you are experiencing. The first thing to check is the fuse that goes to the switch. In some instances, the fuse will cause issues that may prohibit you from using the switch as intended. Some car owners will not feel comfortable doing this type of troubleshooting and will need to hire a professional to assist them. Getting this type of professional guidance will allow you to get to the bottom of the issues that you are experiencing.

Here are a couple of the symptoms that you will experience when it comes time to have your turn signal switch replaced:

  • The indicator lights on both sides will not work
  • The brake lights are not functioning properly
  • The headlamps will not work

Addressing the issues that you have with your turn signal switch in a hurry will allow you to stay safe while navigating the roadways.
