The issue of turn signals not working when the headlights are on is a common issue for drivers. The problem is caused by a malfunction in the wiring or a faulty switch or relay. If this issue occurs, it can be extremely frustrating as it affects the ability to make safe and timely turns. Here we will look at what is causing this problem and how it can be fixed.

The turn signal switch controls the headlights, the interior dome light and other features that may require electrical power to operate. If any of these components are not working properly due to a wiring issue or a faulty switch or relay, then it could cause the turn signals to not work correctly when the headlights are on.

In order to check if there is an issue with the wiring, you will need to do some testing with a digital multi-meter. By doing this, you can determine if there is an interruption in power flow which could be causing the turn signals not to work when the headlights are on. If you have done this and have ruled out any electrical issues then it may be time to take a look at the switch or relay.

If either of these components has gone bad then you will need to get them replaced or repaired in order for your turn signals work correctly again when your headlights are on.

To identify these issues, a power supply deficiency needs to be inspected. This can be done by checking both the relay assembly and fuse to ensure that they are functioning properly. If a short out occurs, it is necessary to check the flasher unit and tag line connections to ensure they are not malfunctioning. Lastly, it is important to test the light switches and turn signal switch for any potential malfunctions of parts.

Faulty Battery Signs

In addition to underlying electrical issues, there may be signs of a faulty battery that could be causing your turn signals not to work with your headlights on. To test for this, it is necessary to scan for any alternator blockage and test both the air hoses and starter for any potential issues.

By thoroughly inspecting all of these components, you should be able to identify any underlying electrical issue that may be preventing your turn signals from working with your headlights on. By resolving this issue, you will have restored your turn signals back to their full functionality.
