I have a 2020 Ford Expedition that I am repairing after a front end accident. The front turn signals don't work... the back ones work just fine, but both front ones don't work. On the turn signal bulb there are two filaments. One lights up when you open the door, the other is for the turn signal. The door ones work fine, the turn signals don't. I tried changing the bulbs, but the problem persists. PLEASE HELP. I need it up and running asap and don't know what to do
