High Beam Issue; Not MFS

[InkdGreaser]

I have a 2001 Sport Trac 4WD. The issue is I have low beams, but when I switch to high beams the headlights turn off. There is no indicator light on the cluster, like it doesn't light up. I've already replaced the MFS and the headlamp switch. I don't have any blown fuses, replaced my bulbs. All my directionals work, and every other light on the truck. I figure I'm probably going to have to trace some wire, but this is my first Sport Trac. Anyone give me pointers on where to start with the wiring? Or, better yet, have any other ideas that are simpler? Haha. Thanks in advance for any help.
Oh yeah, there are no daytime running lights either.

I meant, daytime running lights are not equipped on my rig. Not that I have them and they don't work.
