If all fuses are good, the relays are good, and you replaced the main DRL relay above the glove box, power is likely being lost before the switch.
I attached the headlamp wiring schematic below. Check the wires I highlighted at the switch for power. Also, if you haven't already, confirm there is power to the fuses you checked. Note I had to cut the schematic in half to make it readable. I did overlap the two pics so you can follow from one to the next.
Here are a couple of links you may find helpful when checking:
Let me know what you find or if you have other questions.
Take care and God Bless,
