I had my entire right headlight go completely out due to a dead battery. I tried everything (power cycling, disconnect reconnect) nothing worked I made an appointment with ford 2 weeks later and sure enough a day before the appointment it started working. I would say power cycle the car unplug...
Had her about a year now. And I have loved every second of it. Even made an IG account lol
