Headlights problem on a 95 GA

I recently got arrested for my headlights.
As you maybe know, headlights switch automatically between day/night beam on 95 grand am.
But my night beams stop working.
The switch work fine, my fuses aren't blown, my bulb aren't burned.
I think it's my relay or the daytime running light module.
Is anyone who have an idea where these parts are located?
I can't repair it by myself, I installed my stereo, neon, etc... by myself
Thanks

Welcome to the forum. The DRL's are controlled by the BCM, which is located underneath your dash area on the passenger side. You'll find it - it should be mounted on or next to the wall.
