Why Isn’t My Turn Signal Working?

Have you ever been driving and realized you do not hear the normal turn signal sound when you are trying to make a turn? This is the most common sign that your turn signal is not working and should be addressed as soon as possible because failing to do so could be extremely dangerous.

When it comes to turn signal lights, there are many different things that could go wrong. Use this list to determine if your issue falls into one of these categories:

 One turn signal is not working.

If this is the case, it should be a simple fix, because you are likely dealing with a burnt-out bulb. If you are doing the replacement yourself, be sure to check the socket for corrosion. If you use a Wrench mechanic, they will check that for you and will let you know if there are any further problems.

 Neither turn signal light is working.

If both lights are not working, this is likely a sign of a blow fuse or a dysfunctional flasher. This could also be due to a corroded socket or damaged bulbs, which are a slightly more complicated issue. Not being able to use your turn signals at all extremely dangerous and we recommend avoiding driving as much as possible until one of our mechanics comes out to fix the problem.

 Turn signals do not flash.

If the lights are working fine but are not flashing, this is an issue with the turn signal flasher or turn signal switch. If you want to check this problem out yourself, you will need to access the signal switch electrical connector. We recommend following the detailed instructions in the owner’s manual before attempting any sort of work at home.
Turn signals work but hazards do not. In most cars, you will most likely need to change the flasher or the fuse, or just readjust the connection.

 Turn signal light isn’t turning off.

This can be dangerous for other cars on the road who think that you are constantly trying to turn or do not know where you are actually going. This issue can usually be resolved by replacing the switch, cam, or assembly depending on the nature of the problem and the type of car you drive.

 Signal is blinking too fast.

If your turn signal is blinking more rapidly than normal, this likely means that there is a bulb out on the side. Turn signals rapidly pause the circuit that causes the front and rear lights to flash, but the resistance that controls the timing can fail when one of the bulbs is out or not working properly.

 Signal is blinking too slow.

Having a turn signal that blinks too slow can also be dangerous because it can be confusing for the other cars on the road to know what you are trying to do. This could also be due to a malfunctioning bulb on the side of the car that is impacting the resistance of the circuit.
