2018 Ford 450 interior lights
Interior lights do not work when door is opened, by overhead console
switches, or by remote start.
The owners manual does not indicate the fuse or relay associated with interior
Do you still have warranty coverage? Did you check the bulbs?
Yes I still have warranty coverage. Manual says they are LED to be serviced but dealer. All interior lights are out that’s why I was thinking fuse or relay.
Check all the fuses. It will only take a couple of minutes.
