OK, been to about every post on similar problems. Seems each is a bit different, as is mine.
Headlamps stay on Hi beam, with Hi beam indicator lit, no matter where swich is set.
(Low, Hi or Pull lever to blink Hi)
Ordered multi function switch and installed.
No change in problem...
Relay box under hood does not have daylight relays, so I assume It does not have that option.
Any input my forum friends?

 

Is the truck Heritage (looks like a 1997-2003) or New Body Style?

 

Im a used car lot. Just got this one. Is there badging that says Heritage. Nothing on this one if so. I took a photo. I'll try to attach it.

 

That's new body style.
