You see the white wire leading to BCM from that relay, it's just a ground. Try a redundant ground, jumper wire from the white wire to chassis ground/clean metal part. If the fuse goes hot, nothing wrong with relay. So the problem would be BCM or headlamp switch, maybe wiring circuit to or from? I know testing is a pain, but, I'd rather try to be sure. Some relays that are soldered into fuse box, sometimes I can gently pry the top off and then do some testing. Sometimes if your sure the relay is a problem, you can wire up external relay. I'm not sure how big of a problem that would be?
