I realized one day my turn signals weren’t working how they should. I turned my left signal on and my right signals turned on same goes for if I used my right signal. I already replaced the bulbs and the housing, and a new turn signal switch cause that’s what everyone thought. Now I have no clue. Any help?

Hi and thanks for using 2CarPros.

First, check and confirm the signal flasher relay is working properly. Here are the directions for testing. The attached picture indicates what pins to check and how to check the relay to determine if that is the issue.

Turn Signal Relay Input Test
Remove the dashboard lower panel, then remove the turn signal /hazard relay.

See picture 1

Make the following input tests at the relay holder pins. If all tests prove okay, but the relay fails to work, replace the turn signal/hazard relay.

Brittney, based on what you have already done, I assume you already know this. But just in case, here are a few links that may be helpful:
