Even if you’re just going to the corner store, you need your turn signals to work. Not only is it the law, but it’s also the only way to let other drivers know you’re going to turn.

You could cause an accident if your turn signals don’t work. This could not only hurt you, but it could also do a lot of damage to your car. Make sure your turn signals work to keep this from happening.

Most of the time, you’ll notice if your turn signals aren’t working. Either the dashboard light won’t be on, or you won’t hear the clicking sound. Your turn signals won’t work at all sometimes. Some of the time, they work, but not always. This can be a bother. Before you take your car to a mechanic and pay hundreds of dollars to fix it, see if you can figure out what’s wrong and fix it yourself.

A lot of people don’t know that your car’s turn signal system is linked to a number of other parts. For example, the wiring for your turn signals is the same as that for your brake lights, warning lights, and parking lights.

If something goes wrong with any of these parts, it could affect the rest of the systems. Before you pay someone to tell you what’s wrong, it’s better to have an idea of what could be wrong. It might only cost $10 to fix.

Don’t pay a lot of money for something you could have done yourself. Here, we’ll talk about the five most common reasons why your turn signals don’t always work. We’ll also suggest a way to solve each problem.

Turn Signal Works Sometimes-3

Are Your Turn Signal Light Bulbs Dead?

Light bulbs all burn out in the end. Light bulbs for turn signals should last at least a few years. Most people’s turn signal lights will last as long as the car does. It all depends on how often you use your turn signals and how much you drive. Since these bulbs aren’t too expensive, it would be smart to replace them and see if that fixes the problem. If so, that’s great. If not, you’ll need to keep looking. The situation could be a bit trickier.

Do You Have a Faulty Turn Signal Switch?

The device near your steering wheel that you use to turn your turn signals on and off is called the turn signal switch. If they can’t send a signal to the computer to tell it to turn on the lights, it won’t work. The wiring or the switch could be the problem. If the switch only gets stuck sometimes, you might be able to fix it. But if it’s more than that, you should see a doctor.

Your Bulb Sockets Could Be Oxidized

Eventually, almost every part of your car will start to rust. This is a fancy way of saying “rust.” Rust and dust can cause your turn signals to stop working right. It makes it hard for the bulb to fit into the socket. The best way to avoid this is to clean and fix things regularly. If the problem keeps happening, you might have to take your car to a nearby mechanic.

Maybe You Have a Blown Fuse?

Most people know what it means when a fuse blows. Most of the time, this takes place at your home. If a fuse blows, it could be because you have too many things plugged in. Or, your air conditioner goes too fast and blows a fuse. All you need to do is reset the fuse or flip the main breaker. It’s not so simple when it comes to your car. If you have too many signals going at once, your fuse may blow. Or, if the energy level gets too high, the fuse can melt. If your fuse is blown, you’ll have to get a new one. The good news is that new fuses don’t cost too much. It’s also not hard to do.

Broken Flasher Module – This May Require a Mechanic

turn signal works sometimes

Your turn signal system has something called a flasher module. This is how the power from your car’s battery gets to the turn signal system. If this breaks, your turn signal won’t get any power. Don’t forget that we said earlier that your turn signal system is linked to a lot of other things. They might all go off at the same time. Through a piece of lead, this module is linked to your fuse. It won’t work if this lead breaks or gets damaged. You can’t really take care of this on your own. You’ll have to take it to a mechanic in your area to get it fixed.

Always Use Your Manual to Troubleshoot Your Turn Signal Problems

We can easily tell you about the most common problems with your turn signals. But it’s not always easy to figure out what’s wrong with your system. You might have to find some hidden parts of the turn signal system. You may need to take off the covers, take the steering wheel off, and turn off the airbag. If you don’t, you could set off any of these and make things worse. To do this, you need to look at your service manual.

If you’re not sure how to do this, take it to a nearby mechanic. They will look at your car’s manual or a book called Haynes Manual, which is one of the most common. Since every make and model is different, they will need to make sure they understand your system. So, they can find the problem and fix it in a safe and correct way. This may cost you a couple hundred dollars, but it’s money well spent. If you get in an accident or get a ticket for not having working turn signals, it will cost you a lot more than what it costs to fix.
