2004 F150 Headlight Beam staying on
I have replaced my fog lights with led pods and they worked great with my headlights for about 3 weeks. Since then, my high beams are stuck on and the only way I have light is if I turn just my fog lights on. I have checked fuse and it’s good. Any other suggestions?

Check your headlight relays. They are in the fuse box.

They are listed in the Owners Manual.

I have also checked the relays and switched them out with another and they still aren’t working properly

Can you define what you mean a little better? "High beams stuck on" is a bit vague. Exactly what happens when you do what?

When I turn my headlights all the way on to low beam, they don’t turn on and on my dash it has the high beam symbol showing. It’s like it’s stuck on high beam

Possibly a bad turn signal/high beam stalk on the steering wheel?

I was thinking that as well. Is there anyway to check to see if it’s bad other than that

What happens if you click the stalk to high beam? What about the flash to pass? Do the other functions on the stalk work?

Then my fog lights go off and that’s it. Nothing with my headlights is working.

So, the fog lights are on with the high beams until you move the stalk to the high beam position or flash-to-pass?

The only way the fog lights work is if I have my switch to the running lights on. If I turn my headlights on, high or low, then my fog lights stop working completely

Fog lights are only supposed to work with low beams or with headlights off, that's how they are wired.

I'm betting it's the MFS.
