Good Morning! I want to start off with saying that this forum has been of great help to me in buying my truck and I'm constantly reading up on mods. Thanks to all who make it happen!

Now for the bad....... 1999 f250 SD work xl. Every light outside works INCLUDING BLINKERS. But I do not have brake lights. Installed and tested new brake pedal switch and multifunction steering column switches. Still nothing. Trailer lights also work except brake. Third brake/ bed lights are not functioning either and have new bulbs.

Interior illumination lights not working either. Can't find a fuse that is bad. All wiring appears intact.

Thanks in advance for your help.
