You have to use a heat gun to open up the headlight assembly to replace the strips or replace the whole thing. Have you verified the connector/wiring are good? Proper voltage making it to the headlight assembly?

I know its been a hot minute since this thread has had any activity but I just had the same exact issue come up. Was working on my car and my battery was low so I had to charge it. Start it up then the passenger side DRL's stopped working too. What did you end up doing to fix it?

Im sure you meant reconnecting the battery....yes yes I have about 5 times trying to diagnose this issue. I have no fault codes from the computer in ForScan and no relay or fuses are out. Talked to a Ford dealer and the LED board doesn't exist apparently. Currently in talks with ford themselves because a wiring diagram doesn't exist for the DRL's even tho it's a replaceable board with a harness connecting to it with a removable connector. Service tech himself doesn't know anything either. Nonetheless I've tried. Only a few people have reported the passenger side failing and I want to hear from those people if that's understandable because I have done my troubleshooting lmao

sadly I couldn't track literally anything down, Ford was no help either. No schematics internally at all other than one that didn't help me. I just went with the Diode dynamics replacement. Technically the cheapest option
