Need help with relay (buzzing) noise


Recommended Posts

Just tried to change the headlights for my 2013 edge with an hid kit. I used a can bus ballast with a capacitor and a relay harness. It works perfectly fine when I have to manually turn on/off the headlights. The problem starts when the switch is on Auto during daytime. I just thought the capacitor would solve both the flickering and buzzing problem (of the DRL). There's no flickering noted however the relay is still making this loud, buzzing noise (when on DRL). I've tried a different relay box but same result. I'm pretty sure all the wires are properly connected too. The buzzing sound is just too loud and irritating that I feel like it's gonna explode anytime. I just want to keep the headlights on Auto as I often forget to switch the headlights on if I do it manually. What else do I need to do?
