I have a 3 week old 2022 F250 Kings Ranch 6.7. 1600 miles on it. The passenger side fron turn signal lamp quit working. If you use it , it flases at an increased rate.
I followed the manual on how to get to the bulb and you cant get to it. The LED assembly is completely sealed.
It turns out, you need to schedule an appointment at a Ford dealer. They have to perform a full electrical diagnostic check and submit their findings to Ford for authorization to order a new headlamp assembly under warranty.
You need to ignore the manual and any youtube videos on the front headlamps of the 2022 if LED
Happy thanksgiving to all

 

Thanks for the info. Sooner or later someone else will have this problem and I hope you are can pass this on to them.
