I have a 2006 F150 King Ranch.
All of a sudden my left turn signal stopped working and stays solid. The right signal works fine. The 3rd brake light remains on as well.
When the headlights are turned off, everything functions as normal. When I turn on the headlights is when I have the problems. The signals both work with lights off.
All lights are working.
Could it be the MFS? Short? Fuse?
Thanks
