So, I just had my turn signal switch replaced because it was jammed and my headlights would not turn on. Before being replaced the turn signals worked now that the switch has been replaced my headlights work, but now the turn signals wont work, my hazards work fine. But I get nothing when trying to use the turn signals. I have replaced the fuse thinking that was the problem but unfortunately it didn't help. Any suggestions?

Clearly the first thing that comes to mind is that the new switch is faulty. Any time we have an issue that was not there prior to a part replacement then we have to assume that part is to blame.

So here is a guide on how to replace the turn signal switch in the event you need that:

However, this could be a relay issue but it is unlikely due to the hazard lights functioning properly. They share a relay so if all this work except the turn signals, i would replace the switch again and see what happens.

Let us know if you have other questions. Thanks
