Yeah, if one stopped then the other, likely it's not the HDM. BUT, what did you "try" with the HDM relay? Since our wires are way too small of a gauge for the bulbs, you may check the actual bulb socket or harness for melting plastic or wires. Many people have had to replace the pigtails.

I replaced the HDM with a brand new one and nothing happened. I have checked the bulb socket they are new and just fine. I also contacted a local auto shop and they told me that they would charge me $90 an hour and see if they could figure out what was wrong. Thank you for your answer

switch your high and low beans replays around replace one etc. had three perfectly good working relays but for some reason one of them made my headlights turn off randomly couldnt tell you what i did to fix it other than buying like 4 new relays and constantly changing them around in the fusebox yea i know just sounds dumb but hey it worked

ive gone about 5 months now without a single headlight issue, i also did take my entire fusebox apart after this still no issues
