I'm looking for the headlight relays on my 2020 RAM ProMaster Cargo Van 1500. I've checked all the usual places, but I can't find them

Does anyone know where they are or have a diagram? Any help would be great

RAM moved a lot of that stuff to the BCM, under the lower dash on the driver's side, so now instead of a traditional relay setup, the BCM controls the headlights electronically and that means there's no physical relay to replace if you're having headlight issues, it might be a BCM issue or a wiring problem rather than a relay swap

What he said, or sometimes in the engine bay fuse box near the battery. Check both
