Headlight

I have a 2004 F-250n crew cab, the headlights work on high beam but not the right side on low. Yes the bulb is good and I checked the fuse what else could it be?

Did you test the bulb of just take a visual? Sometimes there can be a hairline break in the element and it wont work even though it looks good. If the element is good get out a test light and start working your way back.
I put a new bulb in and went as far as moving the bulbs around and reversing the high and low positions to double-check. I just thought that maybe there was another control before or after the fuse that might be the culprit. I guess it’s a short if not?

Short, relay or fuse.
