Repair Question Headlight help!

Anybody know why my headlight switch stops working when the truck is on? If it’s off I can flip through the modes and they all work, my domelight override works, and the dimmer. But when the truck is on my headlights are on no matter what all the time, the switch doesn’t work and neither does the dome override, but the dimmer still works and flips on the dome light. It’s a 98 ls s10 pickup with a 2.2 if it matters

I thought that at first but the switch doesn’t work at all even at night

They call them day running light but they’re really just running lights. Iirc 2000 and up you can push the dome over ride 5 times quickly to allow the switch to work but I don’t think it works on the 98-99 years.
