So, i have a situation with my blinkers. Whenever it is dark out, my blinkers and hazards don't work. What might be the issue with this? I have aftermarket LEDs for the bulbs.

Hello,

It sounds like you have a BCM going out. here are the wiring diagrams so you can see how the system works and the BCM location and instructions so you can replace it. You will need to have it programmed, which should cost about $130.00. I would use this guide to check the connections and grounds before doing the BCM to be sure:
